Can I merge multiple managers to produce one MR?

[syphernl]

We have quite a few Terraform repositories within our company. When Hashicorp releases a new version of Terraform this causes manual work for us, even though Renovate does some heavy lifting.

Renovate:

• Updates the .gitlab-ci.yml Docker reference to the new version
• Updates the .terraform-version to the new version
• Does not (yet?) update the version reference in the required_versions section (I have created a feature request for that: Updating terraform required_providers version #8746)

The problem that we are facing is that two separate MR's are being created for this right now. One to update the .gitlab-ci.yml and one to update the .terraform-version.
Can we configure Renovate to create a single MR with both changes?

The documentation on grouping mostly talks about grouping based on package patterns, if I try to go that route with

  {
    packageNames: ['hashicorp/terraform'],
    groupName: 'terraform',
  },

it simply creates two PR's (even though there already were two with the exact same changes) with branch renovate/terraform and renovate/docker-terraform.

Any pointers in what I need to configure to have it create a single MR for both changes? Thanks!

Use packageRules to do matching and then assign a groupName. What are the current branch names which you'd like to see combined into one?

he also needs to override additionalBranchPrefix because docker datasource os overriding it by default

renovate/lib/datasource/docker/index.ts

Line 27 in 01e1f38

additionalBranchPrefix: 'docker-',

I've now changed it to this:

  // Merge MR's updating hashicorp/terraform
  {
    packageNames: ['hashicorp/terraform'],
    groupName: 'terraform',
    additionalBranchPrefix: '',
  },

regex manager i use to update terraform required_version 😉

https://github.com/visualon/renovate-config/blob/main/shared.json#L70-L76

  {
      "fileMatch": ["\\.tf$"],
      "matchStrings": ["required_version\\s*=\\s*\"(?<currentValue>.+?)\""],
      "datasourceTemplate": "docker",
      "versioningTemplate": "hashicorp",
      "depNameTemplate": "hashicorp/terraform"
    }

Ah that's cool! Thanks for sharing 👍🏻
