Using inline bash commands as a task

[Hugh Acland]

Hi

I want to commit a running docker image as a task and use the git head hash for the tag name. In bash I would do this:

docker commit 8d from/remote-animal:$(git rev-parse HEAD | cut -c1-10)

However when I use this command in Go-Cd task it does not like it. How can I achieve this? I guess one way is to have a script on the agent and the call this script, but then this kinda means having to have gotten the script onto the agent in the first place. I thought the whole point of agents is that they are ephemeral? 

thanks

GoCD's Custom task doesn't run inside a shell unfortunately. We also do something like this in our pipelines

<exec command="bash">

  <arg>-c</arg>

  <arg>docker commit 8d from/remote-animal:$(git rev-parse HEAD | cut -c1-10)</arg>

  <runif status="passed" />

</exec>
