Depending on the container you are using, you may want to use this step to prevent builds/deploys from halting when you setup a connection with them:
The authenticity of host 'some-server.wercker.com (188.8.131.52)' can't be established. RSA key fingerprint is ff:ee:dd:cc:bb:aa:99:88:77:66:55:44:33:22:11:00. Are you sure you want to continue connecting (yes/no)?
deploy: steps: - add-to-known_hosts: hostname: ssh.example.com fingerprint: ce:83:e9:7d:02:a4:e3:63:3f:8a:07:cc:d5:d9:bb:cd
Using this step in combination with an SSH key allows you to use that key for SSH operations, such as cloning a private repository:
build: steps: - add-ssh-key: keyname: MYPACKAGE_KEY
Keep in mind that if your environment variables are
MYPACKAGE_KEY_PRIVATEthe keyname should only be
As with environment variables, if the same SSH key has been specified on an organization or application, the lower level will override the higher level (organization < application < pipeline).
Now your SSH key can be used to clone private repositories during a pipeline run. This solution works as long as we clone via SSH (i.e., not by using HTTPS).
