MonoRepo with Linked repostitory

Dave Attard_wdbowj

I have a MonoRepo and am trying to set up bamboo-specs, that will build only the service that is changed.

I have been able to do this with plan repository with change-detection; However, what i would like to do is have one Linked Repository, that all my plans use, and still have the file filter applied so only run the build plan for the folder that changes. I really dont want to set up 100's of "duplicate" linked repos with the change detection on them.

 

If it cant be done with the repo level, is there a change detection task that can be applied that will only run the rest of the tasks if condition is met

 

Repo

- Service1

- Service2

...

 

repositories:
- repo1:
    type: bitbucket-server
    server: Bitbucket
    project: XXXX
    slug: xxxx
    clone-url: 
    public-key: 
    private-key: 
    branch: master
    command-timeout-minutes: '30'
    use-shallow-clones: true
    cache-on-agents: true
    submodules: false
    ssh-key-applies-to-submodules: false
    verbose-logs: false
    fetch-all: false
    lfs: false
    change-detection:
      file-filter-type: include_only
      file-filter-pattern: Service1/.*

Hello @Dave Attard

Having a monolithic architecture with dynamic triggers based on the content that has been modified is something that is not available in Bamboo.

As an alternative, you can set a single Plan that would be triggered on every commit of that mono repo and then Checkout the repository and initiate a Script Task that will analyse the last revision's contents and trigger the required builds in Bamboo over REST API.

For example, the following git command will return the list of the files modified in the HEAD revision:

$ git diff-tree --no-commit-id --name-only -r HEAD

Then, from that output you can make the script realise which Plans are to be triggered, then use the Bamboo REST API to initiate their builds:

• https://developer.atlassian.com/server/bamboo/rest/api-group-api/#api-api-latest-queue-projectkey-buildkey-post

That is a quite simple theory that would work for your case. You may have to extend the script to consider (and trigger) other branches in case you use Plan branches in Bamboo.
