This task requires the following:
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.
If you must have the private SSH key available during the image build (e.g., pulling dependencies) then please remove the private key before the end of the Dockerfile instruction (see the `SSH Key Option' on this page before continuing with the information below).
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'
