Currently, the database migration command is being executed but it seems

As of tag 1.16 of gcr.io/cloudsql-docker/gce-proxy, the currently accepted answer no longer works. Here is a different approach that keeps the proxy in the same step as the commands that need it:

  - id: cmd-with-proxy
    name: [YOUR-CONTAINER-HERE]
    timeout: 100s
    entrypoint: sh
    args:
      - -c
      - '(/workspace/cloud_sql_proxy -dir=/workspace -instances=[INSTANCE_CONNECTION_NAME] & sleep 2) && [YOUR-COMMAND-HERE]'

The proxy will automatically exit once the main process exits. Additionally, it'll mark the step as "ERROR" if either the proxy or the command given fails.

This does require the binary is in the /workspace volume, but this can be provided either manually or via a prereq step like this:

  - id: proxy-install
    name: alpine:3.10
    entrypoint: sh
    args:
      - -c
      - 'wget -O /workspace/cloud_sql_proxy https://storage.googleapis.com/cloudsql-proxy/v1.16/cloud_sql_proxy.linux.386 &&  chmod +x /workspace/cloud_sql_proxy'

Additionally, this should work with TCP since the proxy will be in the same container as the command.
