Automerging merges pull requests automatically if all plans have been
successfully applied.
* Save status of PR's to BoltDB so after each apply, we can check if
there are pending plans.
* Add new feature where we delete successful plans *unless* all plans
have succeeded *if* automerge is enabled. This was requested by users
because when automerge is enabled, they want to enforce that a pull
request's changes have been fully applied. They asked that plans not be
allowed to be applied "piecemeal" and instead, all plans must be
generated successfully prior to allowing any plans to be applied.
In Terraform 0.12 and above, you aren't allowed to set -var foo=bar
flags unless the foo variable is actually defined in code. Previously,
we were setting the following variables:
- atlantis_user
- atlantis_repo
- atlantis_repo_owner
- atlantis_repo_name
- atlantis_pull_num
Users could then use these variables if they wanted to, in their code.
The main use case was to name the assume role session in AWS:
provider "aws" {
assume_role {
role_arn = "arn:aws:iam::ACCOUNT_ID:role/ROLE_NAME"
session_name = "${var.atlantis_user}-${var.atlantis_repo_owner}-${var.atlantis_repo_name}-${var.atlantis_pull_num}"
}
}
This is longer possible in 0.12.
Introduce new `mergeable` requirement, in similar vein to the `approved`
requirement. Ran `make go-generate` to update mocks accordingly.
This addresses issue #43.
Previously we added -var atlantis_repo=runatlantis/atlantis but the '/'
character is not a valid character for the AWS assume role session name.
To fix this, this commit adds -var atlantis_repo_owner=runatlantis and
-var atlantis_repo_name=atlantis (where runatlantis and atlantis would
be the values for the repo the pull request is from ).
* If output is longer than 12 lines, wrap it in markdown folding for
GitLab and GitHub.
* Reformat the Terraform plan output so that the + and - lines show up
highlighted properly when using the diff syntax highlighting
