Many operations require the configuration of an SSH private key within your container(s) (e.g, git clone, rsync, ssh, etc).
While the task seems as simple as copying a private key right into your Docker image, this is considered highly inadvisable.
The suggested practice is to:
Run the following set of commands in the root of your project folder:
# Generate codeship_deploy_key and codeship_deploy_key.pub, configured to not require passphrase docker run -it --rm -v $(pwd):/keys/ codeship/ssh-helper generate "<YOUR_EMAIL>" && \ # Store codeship_deploy_key as a one line entry in codeship.env file under `PRIVATE_SSH_KEY` docker run -it --rm -v $(pwd):/keys/ codeship/ssh-helper prepare && \ # Remove original private key file rm codeship_deploy_key && \ # Encrypt file jet encrypt codeship.env codeship.env.encrypted && \ # Ensure that `.gitignore` includes all sensitive files/directories docker run -it --rm -v $(pwd):/app -w /app ubuntu:16.04 \ /bin/bash -c 'echo -e "codeship.aes\ncodeship_deploy_key\ncodeship_deploy_key.pub\ncodeship.env\n.ssh" >> .gitignore'
