Bitbucket auto deploy to Linux server (DigitalOcean Droplet)

Question

I have encountered a problem while attempting to deploy my code to a Droplet server (running Ubuntu) using BitBucket Pipeline.

I have set the necessary environment variables (SSH_PRIVATE_KEY, SSH_USER, SSH_HOST) and added the public key of the SSH_PRIVATE_KEY to the ~/.ssh/authorized_keys file on the server. When I manually deploy from the server, there are no issues with cloning or pulling. However, during the automatic CI deployment stage, I am encountering the error shown in the attached image.

This is my .yml configuration.

Thanks for helps in advance.

To refer to the values of the variables in defined in the configuration, you script should use $VARIABLE_NAME, not VARIABLE_NAME as that is literally that string.

- pipe: atlassian/ssh-run:latest
  variables:
    SSH_KEY: $SSH_KEY
    SSH_USER: $SSH_USER
    SERVER: $SSH_HOST
    COMMAND: "/app/deploy_dev01.sh"

Also, note some pitfalls exists when using an explicit $SSH_KEY, it is generally easier and safer to use the default key provided by Bitbucket, see Load key "/root/.ssh/pipelines_id": invalid format
