Changing the name of a remote agent in docker
A remote agent running inside a docker container takes the container ID as the name by default as it's based on hostname. The hostname can be modified with
docker run -h myhostname. However even after specifying a new hostname for the container – the name won't change if the
bamboo-agent.cfg.xml is built into the image.
When the remote agent first connects to Bamboo, it sends the specified hostname as its name, which is then registered and stored in Bamboo's database. If the agent's already registered with the server even if you change the hostname it will tie it back registered agents by UID/ID and retain the old name.
Modify the hostname of the container with
docker run -h myhostname <image>. If the name still doesn't change due to an existing
- Rename the Agent from Bamboo Administration > Overview > Agents > Edit (it has to be done every time a new container is run)
- Or delete the
bamboo-agent.cfg.xmlfile from the
<bamboo-agent-home>– this will force the agent to regenerate a new one with a new ID but your old agent will still remain in the list of Agents until removed. You could do this in your docker run command but it's better to make sure this file doesn't exist in the base image (please note, by removing this file the agent will be treated as new and require re-authentication) – so it entirely depends on how you want to automate your swarm.
docker run -h myhostname ...... /bin/bash -c "rm /home/user/bamboo/agent-home/bamboo-agent.cfg.xml"
