### 🚧 Ongoing Development

CB-TB has not reached version 1.0 yet. We welcome any new suggestions, issues, opinions, and contributors!
Please note that the functionalities of Cloud-Barista are not yet stable or secure.
Be cautious if you plan to use the current release in a production environment.
If you encounter any difficulties using Cloud-Barista,
please let us know by opening an issue or joining the Cloud-Barista Slack.

### 🌍 Localization & Globalization

As an open-source project initiated by Korean members,
we aim to encourage participation from Korean contributors during the initial stages of this project.
Therefore, the CB-TB repository will accept the use of the Korean language in its early stages.
However, we hope this project will thrive regardless of contributors' countries in the long run.
To facilitate this, the maintainers recommend using English at least for
the titles of Issues, Pull Requests, and Commits, while accommodating local languages in the contents.

> 💡 **New to CB-Tumblebug?** Follow the [detailed setup guide](#installation--setup-) below for comprehensive instructions.

### Kubernetes Deployment (Beta) ☸️

CB-Tumblebug can also run on Kubernetes via a Helm chart, using `k-` prefixed
commands that mirror the compose verbs:

```bash
make k-up      # install the stack (auto-creates a kind cluster if none is reachable)
make k-init    # register credentials & load assets (same flow as compose)
make k-port-forward   # access API (1323) and MapUI (1324) on localhost
```

> ⚠️ **Beta feature**: the Kubernetes deployment and `make k-*` commands are
> under active development — behavior and command names may change without
> notice. Use with caution (docker compose remains the stable default).
> See [deployments/helm/cb-tumblebug/README.md](deployments/helm/cb-tumblebug/README.md)
> for prerequisites, operations, and troubleshooting.

### (3) Initialize CB-Tumblebug to configure Multi-Cloud info

To provisioning multi-cloud infrastructures with CB-TB, it is necessary to register the connection information (credentials) for clouds, as well as commonly used images and specifications.

- Create `credentials.yaml` file and input your cloud credentials
  - Overview
    - `credentials.yaml` is a file that includes multiple credentials to use API of Clouds supported by CB-TB (AWS, GCP, AZURE, ALIBABA, etc.)
    - It should be located in the `~/.cloud-barista/` directory and securely managed.
    - Refer to the [`template.credentials.yaml`](https://github.com/cloud-barista/cb-tumblebug/blob/main/init/template.credentials.yaml) for the template
  - Create `credentials.yaml` the file

Automatically generate the `credentials.yaml` file in the `~/.cloud-barista/` directory using the CB-TB script

```bash
    cd ~/go/src/github.com/cloud-barista/cb-tumblebug
    ./init/genCredential.sh
    ```

- Input credential data

Put credential data to `~/.cloud-barista/credentials.yaml` ([Reference: How to obtain a credential for each CSP](https://github.com/cloud-barista/cb-tumblebug/wiki/How-to-get-public-cloud-credentials))

```example
    ### Cloud credentials for credential holders (default: admin)
    ### Holder naming rules: only lowercase alphanumeric and underscores [a-z0-9_]
    credentialholder:
      admin:
        alibaba:
          # Example: app_mkv7rgt4d7i4u7zqtzev2mxxxx
          AccessKeyId:
          # Example: CSEHDcHcrUKHw1CuxkJEHPveWRXBGqVqRsxxxx
          AccessKeySecret:
        aws:
          # ex: AKIASSSSSSSSSSS56DJH
          aws_access_key_id:
          # ex: jrcy9y0Psejjfeosifj3/yxYcgadklwihjdljMIQ0
          aws_secret_access_key:
        ...
    ```

- Encrypt `credentials.yaml` into `credentials.yaml.enc`

To protect sensitive information, `credentials.yaml` is not used directly. Instead, it must be encrypted using `encCredential.sh`. The encrypted file `credentials.yaml.enc` is then used by `init.py`. This approach ensures that sensitive credentials are not stored in plain text.
  - Encrypting Credentials

```bash
    init/encCredential.sh
    ```

When executing the script, you have two options: 1) enter your password or 2) let the system generate a random passkey.

Option 1: Entering your password:

![Image](https://github.com/user-attachments/assets/8f051ce8-9282-4e6d-a8ae-af5c831622c7)

Option 2: Letting the system generate a random passkey, which MUST be securely stored in a safe location:

![Image](https://github.com/user-attachments/assets/807511ee-05d9-481e-a191-d1aad2e9aeb2)

If you need to update your credentials, decrypt the encrypted file using `decCredential.sh`, make the necessary changes to `credentials.yaml`, and then re-encrypt it.
  - Decrypting Credentials

```bash
    init/decCredential.sh
    ```

Option 1: If encrypted using option 1, please use the same password to decrypt the file:

![Image](https://github.com/user-attachments/assets/600921fb-cdff-4313-ae4d-266ddd31809b)

Option 2: If encrypted using option 2, enter the passkey to decrypt the file:

![Image](https://github.com/user-attachments/assets/2bb029a4-8dd9-4e1a-8cad-af70ca72e9fd)

- (INIT) Register all multi-cloud connection information and common resources
  - How to register

Refer to [README.md for init.py](https://github.com/cloud-barista/cb-tumblebug/blob/main/init/README.md), and execute the [`init.py`](https://github.com/cloud-barista/cb-tumblebug/blob/main/init/init.py) script by the [`init.sh`](https://github.com/cloud-barista/cb-tumblebug/blob/main/init/init.sh). (enter 'y' for confirmation prompts)
    `init.sh --help` will show the available options.

You can also simply use the `make init` command as follows:

```bash
    cd ~/go/src/github.com/cloud-barista/cb-tumblebug
    make init
    ```

- The credentials in `~/.cloud-barista/credentials.yaml.enc` (encrypted file from the `credentials.yaml`) will be automatically registered (all CSP and region information recorded in [`cloudinfo.yaml`](https://github.com/cloud-barista/cb-tumblebug/blob/main/assets/cloudinfo.yaml) will be automatically registered in the system)
      - Note: You can check the latest regions and zones of CSP using [`update-cloudinfo.py`](https://github.com/cloud-barista/cb-tumblebug/blob/main/scripts/misc/update-cloudinfo.py) and review the file for updates. (contributions to updates are welcome)
    - Common images and specifications recorded in the [`cloudimage.csv`](https://github.com/cloud-barista/cb-tumblebug/blob/main/assets/cloudimage.csv) and [`cloudspec.csv`](https://github.com/cloud-barista/cb-tumblebug/blob/main/assets/cloudspec.csv) files in the [`assets`](https://github.com/cloud-barista/cb-tumblebug/tree/main/assets) directory will be automatically registered.
    - **`init.py` will apply the hybrid encryption for secure transmission of credentials**
      1. Retrieve RSA Public Key: Use the `/credential/publicKey` API to get the public key.
      2. Encrypt Credentials: Encrypt credentials with a randomly generated `AES` key, then encrypt the `AES` key with the `RSA public key`.
      3. Transmit Encrypted Data: Send `the encrypted credentials` and `AES key` to the server. The server decrypts the AES key and uses it to decrypt the credentials.

This method ensures your credentials are securely transmitted and protected during registration. See [init.py](https://github.com/cloud-barista/cb-tumblebug/blob/main/init/init.py#L150) for a Python implementation.
      In detail, check out [Secure Credential Registration Guide (How to use the credential APIs)](https://github.com/cloud-barista/cb-tumblebug/discussions/1773)

- (INIT) Register CSP credentials into OpenBao for MC-Terrarium

`make init` also registers CSP credentials into **OpenBao** (Vault-compatible secrets manager) so that **MC-Terrarium** can access them at runtime via its OpenTofu templates. This happens in the same `init.py` run — no separate step is needed.

```
  ~/.cloud-barista/credentials.yaml.enc
          ↓ init.py (decrypt in-memory)
          ├─→ Tumblebug API  →  CB-Spider  (cloud connections)
          └─→ OpenBao KV v2 (← Terrarium's OpenTofu templates)
  ```

> For a detailed interaction diagram and step-by-step breakdown of the entire `make init` flow, see the **[`make init` Workflow Guide](docs/feature_guide/make-init-workflow.md)**.
  > For full details on OpenBao credential paths, Makefile targets, and troubleshooting, see [init/README.md](https://github.com/cloud-barista/cb-tumblebug/blob/main/init/README.md).

---

### (4) Shutting down and Version Upgrade

- Shutting down CB-TB and related components
  - Stop all containers by `ctrl` + `c` or type the command `docker compose stop` / `docker compose down` / `make down`
    (When a shutdown event occurs to CB-TB, the system will be shutting down gracefully: API requests that can be processed within 10 seconds will be completed)

![image](https://github.com/user-attachments/assets/009e5df6-93cb-4ff7-93c0-62458341c78b)

- In case of cleanup is needed due to internal system errors
    - Check and delete resources created through CB-TB
    - Delete CB-TB, CB-Spider, and MC-Terrarium metadata using the provided script
      ```bash
      cd ~/go/src/github.com/cloud-barista/cb-tumblebug
      make clean-db
      ```
    - For a full reset including OpenBao (requires re-initialization of credentials):
      ```bash
      make clean-all
      ```

- Upgrading the CB-TB & CB-Spider versions

The following cleanup steps are unnecessary if you clearly understand the impact of the upgrade
  - Check and delete resources created through CB-TB
  - Delete CB-TB, CB-Spider, and MC-Terrarium metadata
    ```bash
    cd ~/go/src/github.com/cloud-barista/cb-tumblebug
    make clean-db
    ```
  - Restart with the upgraded version

## How to Build 🛠️

### (1) Setup Prerequisites

- Setup required tools
  - Install: git, gcc, make
    ```bash
    sudo apt update
    sudo apt install make gcc git
    ```
  - Install: Golang
    - Check https://golang.org/dl/ and setup Go
      - Download
        ```bash
        wget https://go.dev/dl/go1.26.2.linux-amd64.tar.gz;
        sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.26.2.linux-amd64.tar.gz
        ```
      - Setup environment

```bash
        echo 'export PATH=/usr/local/go/bin:$HOME/go/bin:$PATH' >> ~/.bashrc
        echo 'export GOPATH=$HOME/go' >> ~/.bashrc
        ```

```bash
        source ~/.bashrc
        echo $GOPATH
        go env
        go version
        ```

---

### (2) Build and Run CB-Tumblebug

#### (2-1) Option 1: Run CB-Tumblebug with Docker Compose (Recommended)

- Run Docker Compose with the build option

To build the current CB-Tumblebug source code into a container image and run it along with the other containers, use the following command:

```bash
  cd ~/go/src/github.com/cloud-barista/cb-tumblebug
  sudo DOCKER_BUILDKIT=1 docker compose up --build
  ```

This command will automatically build the CB-Tumblebug from the local source code
  and start it within a Docker container, along with any other necessary services as defined in the `docker-compose.yml` file. `DOCKER_BUILDKIT=1` setting is used to speed up the build by using the go build cache technique.

#### (2-2) Option 2: Run CB-Tumblebug from the Makefile

- Build the Golang source code using the Makefile

```bash
  cd ~/go/src/github.com/cloud-barista/cb-tumblebug/src
  make
  ```

All dependencies will be downloaded automatically by Go.

The initial build will take some time, but subsequent builds will be faster by the Go build cache.

**Note** To update the Swagger API documentation, run `make swag`
  - API documentation file will be generated at `cb-tumblebug/src/interface/rest/docs/swagger.yaml`
  - API documentation can be viewed in a web browser at http://localhost:1323/tumblebug/api (provided when CB-TB is running)
  - Detailed information on [how to update the API](https://github.com/cloud-barista/cb-tumblebug/wiki/API-Document-Update)

- Set environment variables required to run CB-TB (in another tab)
  - Check and configure the contents of `cb-tumblebug/conf/setup.env` (CB-TB environment variables, modify as needed)
    - Apply the environment variables to the system
      ```bash
      cd ~/go/src/github.com/cloud-barista/cb-tumblebug
      source conf/setup.env
      ```
    - (Optional) Automatically set the TB_SELF_ENDPOINT environment variable (an externally accessible address) using a script if needed
      - This is necessary if you want to access and control the Swagger API Dashboard from outside when CB-TB is running
      ```bash
      cd ~/go/src/github.com/cloud-barista/cb-tumblebug
      source ./scripts/setPublicIP.sh
      ```

- Execute the built cb-tumblebug binary by using `make run`
  ```bash
  cd ~/go/src/github.com/cloud-barista/cb-tumblebug/src
  make run
  ```
