**AEM Compose**

AEMC is a versatile tool for managing Adobe Experience Manager (AEM) instances. 
With a comprehensive set of commands, it simplifies tasks such as working CRX packages, OSGi configurations, JCR repository nodes, and more. 
Its seamless integration with Terraform, Pulumi, and Ansible enhances automation capabilities.

- Reusable core designed to handle advanced dev-ops operations needed to manage AEM instances
- Various distributions based on core for context-specific use cases:
  - [*CLI*](#cli---overview) - for developer workstations, shell scripting
    - [AEM Project Quickstart](https://github.com/wttech/aemc#cli---aem-project-quickstart) - add development environment automation to the existing AEM projects
    - [Docker Example](examples/docker) - for experiments only
  - [*Terraform AEM Provider*](https://github.com/wttech/terraform-provider-aem) - set up with ease higher environments (VMs and AEM instances) in the cloud (AWS, Azure, GCP, etc.)
  - [*Pulumi AEM Provider*](https://github.com/wttech/pulumi-aem-native) - working the same as Terraform AEM Provider but with Pulumi
  - [*Ansible Collection/Modules*](#ansible-collection) - for managing higher AEM environments
    - [Packer Example](https://github.com/wttech/aemc-ansible/tree/main/examples/packer) - starting point for baking AWS EC2 image using Ansible
    - [Local Example](https://github.com/wttech/aemc-ansible/tree/main/examples/local) - development & testing sandbox for AEM Compose project
- Fast & lightweight
- Usable on all operating systems and architectures without pre-installing any dependencies

# Distributions

## CLI - Overview

Provides complete set of commands to comfortably work with CRX packages, OSGi configurations, repository nodes and more.

Key assumptions:

- Idempotent and fast
- Rich configuration options
- Self-describing, both machine & human-readable 
- Multiple input & output formats (text/yaml/json)

Main features:

- easy & declarative setup of:
  - JDK (isolated, version tied to project)
  - AEM instances (run modes, JVM & start opts, env & secret vars, Sling props, custom admin password)
  - OSGi (configurations, bundles, components)
  - Crypto Support, Trust Store, SSL by Default
  - replication agents 
  - any repository nodes
- deploying AEM packages with:
  - efficiently upload with optimized memory usage (constant and independent of package size)
  - automatic workflow toggling - avoiding DAM asset renditions regeneration
  - advanced snapshot handling - avoiding redeploying the same package by checksum verification
  - customizable instance health checking
- building AEM packages with:
  - source code change detection - avoiding rebuilding application when it is not needed (handled by [Taskfile](https://taskfile.dev/usage/#prevent-unnecessary-work))
- making AEM instance backups (with restoring)
  - advanced archive format to speed up performance and storage efficiency ([ZSTD](https://github.com/facebook/zstd) used by default)
  - instance state aware - stopping, archiving then starting again AEM instances automatically (if needed)
- content synchronization between running instance and local file system

Worth knowing:

- On Windows use it with [Git Bash](https://gitforwindows.org/) ([CMD](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/cmd) and [PowerShell](https://learn.microsoft.com/en-us/powershell/scripting/overview) are not supported nor tested)

## CLI - Screenshots

Instance commands:

Package commands:

Setup task:

- AEM instances are provisioned only when the configuration is changed
- AEM dispatcher set up using container engine, redeployed only when there are configuration changes as well
- Health checks executed to confirm the stability of the environment as a whole

## CLI - AEM Project Quickstart

Supported project types:

- with structure based on [Adobe AEM Project Archetype](https://github.com/adobe/aem-project-archetype#usage), compatibility:

| AEM Compose | AEM Project Archetype  |
  |-------------|------------------------|
  | >= 1.2.0    | 41, 42, 43, 47, 48, 51 |

- with any type of structure, however afterwards only a little customizations in *Taskfile.yml* need to be done to reflect configuration related to built AEM application artifact path and AEM dispatcher files location,
- empty folder; the project kind will be needed to be specified explicitly during scaffolding.

---

Run command below to install the AEM Compose tool in your project:

```shell
curl https://raw.githubusercontent.com/wttech/aemc/main/project-install.sh | sh
```

After successful installation, remember to always use the tool via wrapper script in the following way:

```shell
sh aemw [command]
```

Next scaffold the AEM Compose files in the project:

```shell
sh aemw project scaffold
```

Project scaffolding:

- sets up ready-to-use tasks powered by [Task tool](https://taskfile.dev/), which aggregate one or many AEM Compose CLI commands into useful procedures.
- provides configuration for provisioning AEM instances (installing service pack, setting replication agents, etc.).
- provides configuration for running AEM Dispatcher on [Podman](https://podman-desktop.io/) (by default) or [Docker](https://www.docker.com/products/docker-desktop/) (remember to install one of these tools before running the setup task).

To list all available tasks, run:

```shell
sh taskw --list
```

Usually, the first steps to take are:

```shell
sh taskw init
sh taskw setup
```

## IaaC Providers

The tool is designed to be used in Infrastructure as a Code (IaaC) solutions such as [Terraform](https://www.terraform.io/) or [Pulumi](https://www.pulumi.com/).

See separate projects based on AEM Compose:

- Terraform Provider: <https://github.com/wttech/terraform-provider-aem>
- Pulumi Provider: <https://github.com/wttech/pulumi-aem>

## Ansible Collection

The tool is designed to be used in Ansible playbooks and roles.

See a separate project based on AEM Compose: <https://github.com/wttech/aemc-ansible>

## Go Scripting

Consider implementing any application on top of AEM Compose API like using snippet below:

File: *aem.go*

```go
package main

import "fmt"
import "os"
import aemc "github.com/wttech/aemc/pkg"

func main() {
    aem := aemc.DefaultAEM()
    instance, _ := aem.InstanceManager().NewByIDAndURL("remote_author", "http://admin:admin@192.168.1.2:4502")
    changed, err := instance.PackageManager().DeployWithChanged("/tmp/my-package.zip")
    if err != nil {
        fmt.Printf("cannot deploy package: %s\n", err)
        os.Exit(1)
    }
    if changed {
      if err := aem.InstanceManager().AwaitStartedOne(*instance); err != nil {
		  fmt.Printf("instance not stable after deploying package: %s\n", err)
		  os.Exit(1)
      }
    }
    fmt.Println("package deployed properly")
    os.Exit(0)
}
```

Then to run application use command:

```shell
go run aem.go
```

# Dependencies

This tool is written in Go. Go applications are very often self-sufficient which means that they are not relying on platform-specific libraries/dependencies. 
The only requirement is to use proper tool binary distribution for each operating system and architecture.
Check out [releases page](https://github.com/wttech/aemc/releases) to review available binary distributions.

# Configuration

## Defaults

The tool tries to make configuration as much explicit as it could be to allow customization in an easy way.

Below are listed all available configuration options ([source](pkg/project/instance/aem/default/etc/aem.yml)):

```shell

Environment variables could be defined in one or many [dotenv files](https://github.com/wttech/aemc/blob/main/pkg/common/osx/osx.go#L32).

## Overriding default configuration

By default, the VCS-tracked file is loaded (*aem/default/etc*).
However, occasionally developers might want to override the default config file and load a VCS-ignored file instead (*aem/home/etc/aem.yml*).

To do so, run the command:

```shell
sh aemw config init
```

## Configuration precedence

All configuration options specified in file *aem.yml* could be overridden by environment variables.
Simply add prefix `AEM_` then each level of nested YAML object join with `_` and lowercase the name of each object.

For example: `instance.local.quickstart.dist_file` could be overridden by environment variable `AEM_INSTANCE_LOCAL_QUICKSTART_DIST_FILE`

Also note that some configuration options may be ultimately overridden by CLI flags, like `--output-format`.

## Context-specific customization

By default, fail-safe options are in use. However, consider using the configuration options listed below to achieve a more desired tool experience.

### Improving performance

```shell
  export AEM_INSTANCE_PROCESSING_MODE=parallel
  ```

This setting will significantly reduce command execution time. Although be aware that when deploying heavy AEM packages like Service Packs on the same machine in parallel, a heavy load could be observed, which could lead to unpredicted AEM CMS and AEM Compose tool behavior.

### Increasing verbosity

```shell
  export AEM_OUTPUT_VALUE=ALL
  ```

Setting this environment variable will instruct the tool to request from the AEM instance descriptive information about the recently executed command subject.
  For example, if a recently executed command was `sh aemw package deploy my-package.zip -A` the AEM Compose tool after doing the actual package deployment will request from CRX Package Manager the exact information about just deployed package.
  This feature is beneficial for clarity and debugging purposes.

### Installing content packages

To install larger AEM packages that may include content pages, assets, and more, you can adjust the HTTP timeout setting. 
By default, the timeout is set to `10m`, but you have the option to increase it (e.g., to `3h`) or disable it completely (by using `0`).

To set the timeout for a single AEMC command, use the following syntax:

```shell
AEM_INSTANCE_HTTP_TIMEOUT=0 sh aemw package deploy --file my-package.zip
```

It's important to be aware that AEMaaCS also has its own timeout for requests made to the Package Manager UI. For detailed information, please refer to the [documentation](https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/implementing/developer-tools/package-manager.html?lang=en#aemaacs-packages).

To skip the instance health check after running a command that would normally trigger it, `AEM_INSTANCE_CHECK_SKIP` environment variable can be used. This can save a lot of time when deploying a lot of packages sequentially.

To skip the instance health check for a single AEMC command, use the following syntax:

```shell
AEM_INSTANCE_CHECK_SKIP=true sh aemw package deploy --file my-package.zip
```

### Installing packages with troubleshooting

Starting from version 1.4.0 (see [#177](https://github.com/wttech/aemc/pull/177)), AEMC now supports AEM package installations using an HTML report serving endpoint, similar to CRX Package Manager's. While this method may result in slightly extended installation times, it provides a comprehensive HTML report detailing the package installation process.

This new feature offers two distinct modes for leveraging its benefits:

1. Saving HTML report to file:

```shell
   AEM_INSTANCE_PACKAGE_INSTALL_HTML_ENABLED=true sh aemw package deploy --file my-package.zip
   ```

2. Direct console output of HTML report:

```shell
   AEM_INSTANCE_PACKAGE_INSTALL_HTML_ENABLED=true AEM_INSTANCE_PACKAGE_INSTALL_HTML_CONSOLE=true sh aemw package deploy --file my-package.zip
   ```

# Concepts

## Local vs Remote Instances

AEMC distinguishes between **local** and **remote** AEM instances:

| Type | Description | Operations |
|------|-------------|------------|
| **Local** | Instances running on developer's machine, fully managed by AEMC | Create, Start, Stop, Delete, Backup, filesystem access, JVM options, run modes |
| **Remote** | Any AEM instance accessible via HTTP (cloud, VMs, etc.) | HTTP-based operations only: packages, OSGi, repository, replication |

Commands like `instance create`, `start`, `stop`, `delete`, `backup` operate only on local instances. Commands like `package deploy`, `osgi config`, `repo node` work with any instance.

## Instance ID Naming Convention

Each instance has a unique ID following the pattern: **`{location}_{role}[_{classifier}]`**

| Component | Required | Values | Description |
|-----------|----------|--------|-------------|
| **location** | Yes | `local`, `int`, `stg`, `prod`, or custom | Environment where instance runs |
| **role** | Yes | `author`, `publish` | AEM instance role |
| **classifier** | No | `1`, `2`, `preview`, or custom | Distinguishes multiple instances with same location and role |

> **⚠️ Important:** The `local` location prefix is **required** for local instance management commands (`aem instance create`, `start`, `stop`, `launch`, `delete`, `backup`, etc.). 
> 
> Instances with any other location (e.g., `int_`, `stg_`, `prod_`) are treated as **remote** and will be **skipped** by these commands, even if their `http_url` points to localhost.

### Example Instance IDs

| ID | Description |
|----|-------------|
| `local_author` | Local author instance (developer machine) |
| `local_publish` | Local publish instance (developer machine) |
| `int_author` | Integration environment author |
| `int_publish` | Integration environment publish |
| `int_publish_preview` | Integration publish preview instance |
| `stg_author` | Staging environment author |
| `prod_publish_1` | Production publish instance #1 |
| `prod_publish_2` | Production publish instance #2 |
| `prod_author_us` | Production author for US region |

### Using Instance IDs

Instance IDs can be used in multiple places:

**1. CLI flags:**
```shell
# Target specific instance by ID
sh aemw package deploy --file my-package.zip --instance-id local_author

# Target by URL (ad-hoc)
sh aemw package deploy --file my-package.zip --instance-url http://localhost:4502

# Filter by role
sh aemw instance status --instance-author   # Only author instances
sh aemw instance status --instance-publish  # Only publish instances
```

**2. Configuration in `aem.yml`:**
```yaml
instance:
  config:
    local_author:
      http_url: http://127.0.0.1:4502
      user: admin
      password: admin
      run_modes: [ local ]
    local_publish:
      http_url: http://127.0.0.1:4503
      user: admin
      password: admin
    int_author:
      http_url: https://author.int.example.com
      user: admin
      password: ${AEM_INT_PASSWORD}
    int_publish:
      http_url: https://publish.int.example.com
      user: admin
      password: ${AEM_INT_PASSWORD}
```

**3. Environment variables** (override config):
```shell
# Activate/deactivate specific instances
export AEM_INSTANCE_CONFIG_LOCAL_AUTHOR_ACTIVE=true
export AEM_INSTANCE_CONFIG_LOCAL_PUBLISH_ACTIVE=false
export AEM_INSTANCE_CONFIG_INT_AUTHOR_ACTIVE=true
```

# Examples

## Managing Local Instances

```shell
# Create and start local AEM instances
sh aemw instance create
sh aemw instance start

# Or do both in one command
sh aemw instance launch

# Check instance status
sh aemw instance status

# Stop instances
sh aemw instance stop

# Delete instances (removes all data)
sh aemw instance delete
```

## Deploying Packages

```shell
# Deploy a single package
sh aemw package deploy --file my-package.zip

# Deploy to specific instance
sh aemw package deploy --file my-package.zip --instance-id local_author

# Deploy multiple packages
sh aemw package deploy --file pkg1.zip --file pkg2.zip

# Deploy from URL
sh aemw package deploy --url https://example.com/my-package.zip
```

## OSGi Configuration

```shell
# List all bundles
sh aemw osgi bundle list

# Check specific bundle status
sh aemw osgi bundle read --symbolic-name com.example.core

# Set OSGi configuration
sh aemw osgi config save --pid com.example.MyService --input-string "enabled: true"
```

## Repository Operations

```shell
# Read node properties
sh aemw repo node read --path /content/my-site

# Copy content between instances
sh aemw content copy --path /content/my-site --instance-target-id local_publish
```

## Instance Backups

Backups allow you to save and restore the complete state of local AEM instances.

**Format:** Backups use [Zstandard (zstd)](https://github.com/facebook/zstd) compression - optimized for excellent compression ratio with very fast decompression speed. Files are stored in `aem/home/var/backup` directory with `.aemb.tar.zst` extension.

**Automatic instance handling:** All backup commands automatically stop running instances before operation and restart them afterwards. No manual stop/start is required.

### Basic Commands

```shell
# List all available backups
sh aemw instance backup list

# Create backup of a single instance
sh aemw instance backup make --instance-id local_author

# Create backup with custom file path
sh aemw instance backup make --instance-id local_author --file my-backup.aemb.tar.zst

# Restore instance from backup (instance must not exist)
sh aemw instance backup use --instance-id local_author

# Restore from specific backup file
sh aemw instance backup use --instance-id local_author --file my-backup.aemb.tar.zst

# Restore and delete existing instance first
sh aemw instance backup use --instance-id local_author --delete-created
```

### Backup & Restore Cycle

Backups enable safe experimentation - break your instance, restore in 10-15 minutes:

```shell
# 1. Save current state before experimenting
sh aemw instance backup perform

# 2. Experiment freely (install packages, change configs, break things...)
# ...

# 3. Something went wrong? Delete and restore from backup
sh aemw instance delete --kill
sh aemw instance backup restore
```

Use cases:
- Safe experimentation with risky configurations or packages
- Quick recovery from broken instances without full reinstall
- Testing different AEM versions or configurations
- Sharing pre-configured instances via cloud storage (S3, GCS, Azure Blob)

**Backup file naming:** `{role}[-{classifier}]-{aem_version}-{timestamp}.aemb.tar.zst`  
**Example:** `author-6.5.21-20260209-143022.aemb.tar.zst`

## Replication agents

1. Configuring publish agent on AEM author:

```shell
    sh aemw repl agent setup -A --location "author" --name "publish" --input-string "
    enabled: true
    transportUri: http://localhost:4503/bin/receive?sling:authRequestLogin=1
    transportUser: admin
    transportPassword: admin
    userId: admin
    "
    ```

2. Configuring flush agent on AEM publish:

```shell
    sh aemw repl agent setup -P --location "publish" --name "flush" --input-string "
    enabled: true
    transportUri: http://localhost/dispatcher/invalidate.cache
    protocolHTTPHeaders:
    - 'CQ-Action: {action}'
    - 'CQ-Handle: {path}'
    - 'CQ-Path: {path}'
    - 'Host: flush'
    "
    ```
   If needed, update `localhost` to the value on which AEM dispatcher is available, e.g.`localhost:8080`.

## Crypto Support

AEM Compose supports managing Crypto Support for encrypting/decrypting sensitive values.

### Setup keys

To set up Crypto keys (required for encryption/decryption to work consistently across environments):

```shell
sh aemw crypto setup --hmac-file aem/home/lib/crypto/data/hmac --master-file aem/home/lib/crypto/data/master
```

### Protect (encrypt) a value

```shell
sh aemw crypto protect --value "secret"
```

### Unprotect (decrypt) a value

> **Note:** Unprotect is only available on AEM 6.5 LTS and AEM Cloud SDK.

```shell
sh aemw crypto unprotect --value "{encrypted_value}"
```

## SSL by Default

AEM Compose supports *SSL by Default* feature of AEM.

This feature requires:
- certificate file in PEM format
- private key file in DER or PEM format
- password for keystore (has to be the same for each invocation of the tool)
- password for truststore (can be different for each invocation of the tool)
- hostname for HTTPS connector (used by AEM to check if the setup was successful; has to be reachable by AEM)
- port for HTTPS connector

To set up *SSL by Default*, run:

```shell
sh aemw ssl setup \
   --instance-author
   --keystore-password password \
   --truststore-password password1 \
   --certificate-file localhost.crt \
   --private-key-file localhostprivate.key \
   --https-hostname localhost \
   --https-port 8443

sh aemw ssl setup \
   --instance-publish
   --keystore-password password \
   --truststore-password password1 \
   --certificate-file localhost.crt \
   --private-key-file localhostprivate.key \
   --https-hostname localhost \
   --https-port 9443
```

Above example uses the self-signed certificate created as per the AEM docs.

See the reference documentation: [AEM 6.5 > Administering Guide > SSL by Default](https://experienceleague.adobe.com/docs/experience-manager-65/administering/security/ssl-by-default.html?lang=en)

For local environment remember to set different port numbers for author and publish instances.

## Global Trust Store

AEM Compose supports managing the trust store of AEM instances.

This feature supports:

- creation of the general trust store if it does not exist
    ```shell
    sh aemw gts create --password PASSWORD_HERE -A
    ```

- getting the general trust store status
    ```shell
    sh aemw gts status -A
    ```

- adding a certificate to the general trust store
    ```shell
    sh aemw gts certificate add --path <path> -A
    ```
  
This command will add a certificate to the general trust store only if not exists in trust store and will return the alias of the certificate.
Command `certificate add` supports certificates in PEM and DER formats.

- reading a certificate from the general trust store (by alias)
    ```shell
    sh aemw gts certificate read --alias <alias> -A
    ```

- removing a certificate from the general trust store (by alias)
    ```shell
    sh aemw gts certificate remove --alias <alias> -A
    ```

# Troubleshooting

## Migration from Gradle plugins

If you're migrating from [Gradle AEM Plugin](https://github.com/wttech/gradle-aem-plugin) you may run into issue with setting up dispatcher.
In case of error when running task dispatcher:start or dispatcher:setup:

```
2024-01-22 16:37:23 dispatcher  | 2024/01/22 15:37:23 Dispatcher configuration validation failed:
2024-01-22 16:37:23 dispatcher  | 2024/01/22 15:37:23   /mnt/dev/src/conf.d/variables/default.vars: lstat /etc/httpd.extra: no such file or directory
2024-01-22 16:37:23 dispatcher  |
2024-01-22 16:37:23 dispatcher  | ERROR Mon Jan 22 15:37:23 UTC 2024 Configuration invalid, please fix and retry,
2024-01-22 16:37:23 dispatcher  |               Line numbers reported are correct for your configuration files.
```

Check if there is a broken symlink/file in `dispatcher/src/variables/default.vars`. If the file exists, delete it and
run the task again.

## Exception while unpacking dispatcher on Linux

If you're setting up your instance for the first time on a Linux OS (i.e. Ubuntu with Gnome Shell), you may stumble upon the following error:

```
