Tooling to rotate the Diego Instance Identity Certificate Authorities for Tanzu Application Service (TAS) 2.4, 2.5, and 2.6.
Running TAS and think this might help? Check out the user docs site.
This project uses Go 1.15+ and Go modules. Clone the repo to any directory.
go test ./... to run the tests.
Build the project by running go build in the project root.
To cross compile, set the GOOS and GOARCH environment variables.
For example, to compile a Linux binary run:
$ GOOS=linux GOARCH=amd64 go build
You can view release notes and download artifacts from the project's releases page.
To create a release, simply create and push a new semver tag starting with v:
$ git tag v0.2.0
$ git push --tags
A Github Action will pick up this tag and create a draft release. Navigate to the releases page, find the draft, enter any release notes, and publish!
Since one of the goals for this tool is to be able to rotate certificates without downtime, we must prove that any changes made to the tool don't negatively impact running apps or the cloud controller API.
To measure the uptime of these components we use a tool called Uptimer. Since this tool must be run on the Operations Manager VM you'll need to run uptimer from another machine. To do this likely need to run this tool separately from uptimer and use uptimer with a configuration that waits.
