Continuous Delivery Via SSH With Docker

Estimated Reading Time: 2 mins

To follow this tutorial on your own computer, please install the jet CLI locally first.

Using SSH/SCP To Deploy

To deploy using SSH and SCP with Codeship Pro, you will need to create a container that can connect to your server via SSH. Then, you will pass this container the necessary deployment commands.

To do this you need to set up an encrypted SSH Key that is available as an environment variable and can be written to the .ssh folder.

Creating Your SSH Key

The following command will create two files in your local repository. keyfile.rsa contains your private key that we will encrypt and put into your repository. This encrypted file will be decrypted on Codeship as part of your build. The second file can be added to services that you want to access.

ssh-keygen -t rsa -b 4096 -C "" -f keyfile.rsa

Now you have to copy the content of keyfile.rsa into an environment file sshkey.env. Make sure to replace newlines with \n so the whole SSH key is in one line. The following is an example of ssh_key.env.


After preparing the sshkey.env file we can encrypt it with Jet. Follow the encryption tutorial to turn the sshkey.env file into a sshkey.env.encrypted file.

You can then add it to a service with the encrypted_env_file option. It will be automatically decrypted on Codeship.

  build: .
  encrypted_env_file: sshkey.env.encrypted

Using The Key During The Build

Before running a command that needs SSH available make sure to run the following commands in that container. They will set up the SSH key so you can access external services.

mkdir -p "$HOME/.ssh"
echo -e $PRIVATE_SSH_KEY >> $HOME/.ssh/id_rsa

Deploying Your Code

Once you’ve established your SSH connection, you will want to deploy your code. This is accomplished via your codeship-steps.yml file by using SSH deployment commands with your authenticated container.

- service: ssh
  command: scp -rp .
