# CircleCI dynamic continuation orb

[![CircleCI](https://dl.circleci.com/status-badge/img/gh/emmeowzing/dynamic-continuation-orb/tree/main.svg?style=svg)](https://dl.circleci.com/status-badge/redirect/gh/emmeowzing/dynamic-continuation-orb/tree/main)

This orb is a merger of CircleCI's [path-filtering](https://circleci.com/developer/orbs/orb/circleci/path-filtering) and [continuation](https://circleci.com/developer/orbs/orb/circleci/continuation) orbs. It enables engineers to create configs under `.circleci/` that only run when there are code changes in coinciding directory paths. Directory-targeted dynamically-executed pipelines offer engineers reduced execution time, and by extension, reduced CI costs.

This orb is based on a [published example](https://github.com/circle-makotom/circle-advanced-setup-workflow) of advanced configuration with continuations from CircleCI.

See my [article on Medium](https://medium.com/@ejd2385/dynamic-continuations-in-circleci-d7516ae5c6f2) about dynamic continuations for a simple introduction to using this orb.

For users familiar with GitHub actions, this orb is analogous to the [paths-filter](https://github.com/dorny/paths-filter) action.

## Usage

Get up-and-running with dynamically continued pipelines in these 4 steps:

1. Add this orb, a `continue` job to your CI config (`.circleci/config.yml`), and the `setup` keyword, such as

```shell
   setup: true

orbs:
     dynamic: bjd2385/dynamic-continuation@<version>

workflows:
     on-commit:
       jobs:
         - dynamic/continue:
             base-revision: main
             context: circleci
   ```

> ***Note:** pipeline config files under `.circleci/` are automatically detected by default (cf. [`auto-detect`](https://circleci.com/developer/orbs/orb/bjd2385/dynamic-continuation#jobs-continue) in the documentation).*

2. Enable **setup workflows** in your project under **Advanced Settings**.

3. The `circleci` context in your organization must have two environment variables set for the orb to reference, including
    - `CIRCLE_ORGANIZATION` (in my case, this is set to `bjd2385`), and
    - `CIRCLE_TOKEN`, which contains your CircleCI API token.

4. Move workflows to their new configs in `.circleci/<config-name>.yml`. Configs should be complete and pass a `circleci config validate`-check.

## How it works

The orb will automatically detect and run a workflow (we'll call it `<module>`) if any of the following conditions are met.

1. If `.circleci/<module>.yml` changes (this is configurable, enabled by default).
2. If changes have been detected within the `<module>/`'s directory on your branch against the repository's default branch (defaults to `main`). See [below](#filtering-or-ignoring-changed-files) on how to filter out CI runs from specific changed files.
3. If, following merge to the default branch, there are changes to `.circleci/<module>.yml` or under `<module>/`, when diffing against the former commit (you must perform a merge commit for this to work properly).

These conditions can be overridden, and all workflows forced to run, if the `force-all` parameter is set to `true` on the `continue` job.

### Examples

#### Basic directory layout

If you have a directory layout

```shell
.circleci/config.yml
terraform/
scripts/
src/
```

with the addition of this orb, a user could define targeted configs

```shell
.circleci/config.yml
.circleci/terraform.yml  # targets changes under the 'terraform/' directory
.circleci/scripts.yml    # targets changes under the 'scripts/' directory
.circleci/src.yml        # targets changes under the 'src/' directory
terraform/
scripts/
src/
```

The `dynamic/continue` workflow would look like

```yaml
setup: true

orbs:
  dynamic: bjd2385/dynamic-continuation@<version>

workflows:
  on-commit:
    jobs:
      - dynamic/continue:
          context: circleci
          modules: |
            /terraform
            /scripts
            /src
```

Once again, the workflows will only execute if any code changes are introduced to the containing "module".

For example: if no changes are made on your branch within the `terraform/` directory, the `.circleci/terraform.yml` CI config will not be executed.

</details>

#### Nested directories

Let's build off of the directory layout above, but add some environments.

```shell
.circleci/config.yml
terraform/
  development/
  production/
  staging/
scripts/
src/
  pkg1/
  pkg2/
```

We may write further targeted configs

```shell
.circleci/config.yml
.circleci/terraform.development.yml   # target specific changes under 'terraform/development/'
.circleci/terraform.production.yml    # target specific changes under 'terraform/production/'
.circleci/terraform.staging.yml       # target specific changes under 'terraform/staging/'
.circleci/scripts.yml
.circleci/src.pkg1.yml                # target specific changes under 'src/pkg1/'
.circleci/src.pkg2.yml                # target specific changes under 'src/pkg2/'
```

with a corresponding `dynamic/continue` workflow in our standard `config.yml`

```yaml
setup: true

orbs:
  dynamic: bjd2385/dynamic-continuation@<version>

workflows:
  on-commit:
    jobs:
      - dynamic/continue:
          context: circleci
          modules: |
            /terraform/development
            /terraform/production
            /terraform/staging
            /scripts
            /src/pkg1
            /src/pkg2
```

Note that the filenames denote additional directory structure with dots `.`, whereas our modules may contain dots `.` or slashes `/`. Thus, the following list of modules is also valid, albeit potentially harder to follow.

```yaml
modules: |
  terraform.development
  terraform.production
  terraform.staging
  scripts
  src.pkg1
  src.pkg2
```

</details>

#### Filtering, ignoring and including file changes

At times, there may be files that change in modules that should _not_ cause workflows to run. These could include, as an example, updated markdown or README-like files.

To solve this problem, the orb has the ability to read an optional `.gitignore`-like filter on each module, named `.circleci/<module>.ignore`, to prevent detected changed files on your PR from enabling workflows.

</details>

##### Ignore file changes

Starting with the same directory layout as above, we could add `.gitignore`-like files

```shell
.circleci/config.yml
.circleci/terraform.yml
.cirlceci/terraform.ignore  # optionally ignore changes under 'terraform/' directory
.circleci/scripts.yml
.cirlceci/scripts.ignore    # optionally ignore changes under 'scripts/' directory
.circleci/src.yml
.cirlceci/src.ignore        # optionally ignore changes under 'src/' directory
terraform/
scripts/
src/
```

These files are automatically referenced, and do not need to be explicitly specified, with a job as

```yaml
workflows:
  on-commit:
    jobs:
      - dynamic/continue:
          context: circleci
          # auto-detect: true
```

or, exactly the same as above.

</details>

##### Include additional file changes

We can create additional pipeline file change dependencies throughout the repo within the same `*.ignore`-files. For example, suppose we have a subdirectory `scripts/terraform/`, and we want changes to files under this subdirectory to enable the pipeline defined in `.circleci/terraform.yml`; we can add

```text
!scripts/terraform/*
```

to `.circleci/terraform.ignore`, as described in the [Git documentation](https://git-scm.com/docs/gitignore#_pattern_format).

</details>

#### Specify an alternate workflow for your repository's root directory

It is possible to run a workflow targeting the root of a repository's directory structure, offering overlapping workflows and more flexibility on file changes when paired with the above strategies. We can accomplish this by specifying `.` or `/` as a module. For example,

```yaml
workflows:
  on-commit:
    jobs:
      - dynamic/continue:
          context: circleci
          auto-detect: true
          root-config: app  # Defaults to 'app.yml' and 'app.ignore' under .circleci/, should the orb detect a '.'- or '/'-root module
```

Note that this requires you define an `app.yml` (though this root config's name is configurable), at  minimum, under `.circleci/`, for the orb to process.

</details>

## Config validation with `pre-commit`

Standard CircleCI config validation pre-commit hooks will only validate the default config at `.circleci/config.yml`. Please use this project's pre-commit hook to validate any additional configs you've created.

Append the following to your `.pre-commit-config.yaml` -

```yaml
- repo: https://github.com/bjd2385/dynamic-continuation-orb
    rev: v<version>
    hooks:
      - id: circleci-config-validate
```

You must have the [`circleci`](https://circleci.com/docs/2.0/local-cli/) CLI installed.

## Development

This orb has been developed in _unpacked_ form. You may view its packed source with

```shell
yarn orb:pack  # creates a file 'orb.yml'
```

Validate an orb definition with

```shell
yarn orb:validate
```

When you're done with development, you may clean up the packed source with

```shell
yarn orb:clean
```

### `pre-commit`

This repository uses `pre-commit` to uphold certain code styling and standards. You may install the hooks listed in [`.pre-commit-config.yaml`](.pre-commit-config.yaml) with

```shell
yarn install:pre-commit-hooks
```
