Run the Kubernetes Agent locally (PREMIUM SELF)

You can run kas and agentk locally to test the Kubernetes Agent yourself.

Create a cfg.yaml file from the contents of config_example.yaml, or this example:

agent:
 listen:
    network: tcp
    address: 127.0.0.1:8150
    websocket: false
  gitops:
    poll_period: "10s"
gitlab:
  address: http://localhost:3000
  authentication_secret_file: /Users/tkuah/code/ee-gdk/gitlab/.gitlab_kas_secret

Create a token.txt. This is the token for the agent you created. This file must not contain a newline character. You can create the file with this command:
```
echo -n "<TOKEN>" > token.txt
```

Start the binaries with the following commands:

# Need GitLab to start
gdk start
# Stop GDK's version of kas
gdk stop gitlab-k8s-agent

# Start kas
bazel run //cmd/kas -- --configuration-file="$(pwd)/cfg.yaml"

In a new terminal window, run this command to start agentk:

bazel run //cmd/agentk -- --kas-address=grpc://127.0.0.1:8150 --token-file="$(pwd)/token.txt"

You can also inspect the Makefile for more targets.

To learn more about how the repository is structured, see GitLab Kubernetes Agent repository overview.

Run tests locally

You can run all tests, or a subset of tests, locally.

To run all tests: Run the command make test.
To run all test targets in the directory: Run the command bazel test //internal/module/gitops/server:all.

You can use * in the command, instead of all, but it must be quoted to avoid shell expansion: bazel test '//internal/module/gitops/server:*'.
To run all tests in a directory and its subdirectories: Run the command bazel test //internal/module/gitops/server/....

Run specific test scenarios

To run only a specific test scenario, you need the directory name and the target name of the test. For example, to run the tests at internal/module/gitops/server/module_test.go, the BUILD.bazel file that defines the test's target name lives at internal/module/gitops/server/BUILD.bazel. In the latter, the target name is defined like:

go_test(
    name = "server_test",
    size = "small",
    srcs = [
        "module_test.go",

The target name is server_test and the directory is internal/module/gitops/server/. Run the test scenario with this command:

bazel test //internal/module/gitops/server:server_test

KAS QA tests

This section describes how to run KAS tests against different GitLab environments based on the GitLab QA orchestrator.

Status

The kas QA tests currently have some limitations. You can run them manually on GDK, but they don't run automatically with the nightly jobs against the live environment. See the section below to learn how to run them against different environments.

Prepare

Before performing any of these tests, if you have a k3s instance running, make sure to stop it manually before running them. Otherwise, the tests might fail with the message failed to remove k3s cluster.

You might need to specify the correct Agent image version that matches the kas image version. You can use the GITLAB_AGENTK_VERSION local env for this.

Against `staging`

Go to your local qa/qa/service/cluster_provider/k3s.rb and comment out this line and this line. We don't allow local connections on staging as they require an admin user.
Ensure you don't have an EE_LICENSE env var set as this would force an admin login.
Go to your GDK root folder and cd gitlab/qa.
Login with your user in staging and create a group to be used as sandbox. Something like: username-qa-sandbox.
Create an access token for your user with the api permission.

Replace the values given below with your own and run:

GITLAB_SANDBOX_NAME="<THE GROUP ID YOU CREATED ON STEP 2>" \
GITLAB_QA_ACCESS_TOKEN="<THE ACCESS TOKEN YOU CREATED ON STEP 3>" \
GITLAB_USERNAME="<YOUR STAGING USERNAME>" \
GITLAB_PASSWORD="<YOUR STAGING PASSWORD>" \
bundle exec bin/qa Test::Instance::All https://staging.gitlab.com -- --tag quarantine qa/specs/features/ee/api/7_configure/kubernetes/kubernetes_agent_spec.rb

Against GDK

Go to your qa/qa/fixtures/kubernetes_agent/agentk-manifest.yaml.erb and comment out this line and uncomment this line. GDK's kas listens on grpc, not on wss.
Go to the GDK's root folder and cd gitlab/qa.

On the contrary to staging, run the QA test in GDK as admin, which is the default choice. To do so, use the default sandbox group and run the command below. Make sure to adjust your credentials if necessary, otherwise, the test might fail:

GITLAB_USERNAME=root \
GITLAB_PASSWORD="5iveL\!fe" \
GITLAB_ADMIN_USERNAME=root \
GITLAB_ADMIN_PASSWORD="5iveL\!fe" \
bundle exec bin/qa Test::Instance::All http://gdk.test:3000 -- --tag quarantine qa/specs/features/ee/api/7_configure/kubernetes/kubernetes_agent_spec.rb
