Docker compose files

Some docker compose templates for various services

Testing environment

To test the templates and adjust them before deployment on production, use Multipass

Prerequisite:

• Visual Studio Code (VS Code)
• VS Code integrated terminal (already built in VSCode)
• Remote SSH extension for VS Code
• Installed Multipass (read how to)

Now open VS Code and

1. Open Terminal in VS Code
2. Create a new RSA key with

ssh-keygen -t rsa

3. Copy the content of the .pub key you just created
4. Create a cloud-init YAML file named vscode-multipass.yaml containing the following (replacing with your public key that you generated)

groups:
  - vscode
runcmd:
  - adduser ubuntu vscode
ssh_authorized_keys:
  - ssh-rsa <public key>

5. Now launch a Docker Image based multipass container named vscode that will include our ssh key using the cloud init file we created:

multipass launch docker --cloud-init vscode-multipass.yaml --name vscode

6. Once it is deployed, grab the IP address of the vscode instacne we created

multipass info vscode | grep IPv4

7. (optional) add the IP address with a testing domain name (e.g. docker.local) in your etc/host file to avoid typing an IP address
8. Click the Open a Remote Window and add the host by following the prompts and entering the IP address (or the testing domain) of the vscode instance that you deployed
