1. In repository, create ssh key pair under Settings > Pipelines > SSH Keys
2. Add public key to through Google Cloud Platform compute engine admin console. Can't just add to ~/.ssh/authorized_keys because GCP must have some firewall settings that can't be bypassed.
3. Optional: Add public key to repository under General > Access Keys. (Don't know if this is necessary though)
4. Add deployment step to bitbucket-pipelines.yml.

Example file:

To write the output of a command to a file, there are basically 10 commonly used ways.

Please note that the n.e. in the syntax column means "not existing".

          || visible in terminal ||   visible in file   || existing
  Syntax  ||  StdOut  |  StdErr  ||  StdOut  |  StdErr  ||   file   
==========++==========+==========++==========+==========++===========
    >     ||    no    |   yes    ||   yes    |    no    || overwrite
    >>    ||    no    |   yes    ||   yes    |    no    ||  append
