How to build

Build it using the standard go build command.

go build github.com/giantswarm/prometheus-meta-operator

How to update upstream code

We store modified upstream code for our own usage.

• pkg/alertmanager/config
• pkg/prometheus/common/config

Initial upstream setup

Add the upstream git repository:

$ git remote add alertmanager https://github.com/prometheus/alertmanager.git

On first run commands are the same as for Upgrade except for git subtree merge which has to be replaced with:

$ git subtree add --squash -P pkg/alertmanager/config alertmanager-config

Upgrade

# add upstream tags
$ git tag -d $(git tag -l)
$ git fetch alertmanager

$ git checkout v0.22.2
$ git subtree split -P config/ -b alertmanager-config
$ git checkout -b alertmanager-0.22.2 origin/master
$ git subtree merge --message "Upgrade alertmanager/config to v0.22.2" --squash -P pkg/alertmanager/config alertmanager-config
# fix conflicts (the usual way) if any

# restore local tags
$ git tag -d $(git tag -l)
$ git fetch

# push for review
$ git push -u origin HEAD

/!\ Do not merge with squash, once approved merge to master manually.
/!\ We need to preserve commit history otherwise following git subtree commands won't work.
$ git checkout master
$ git merge --ff-only alertmanager-0.22.2
$ git push
