Hi, we currently set up the gitlab runner on our GKE cluster. When trying to run the UI integration tests in the pipeline, which will take quite a lot cpu/memory, so I set up a dedicated node and use taint to make the runner only started in the specific node. That is all working but when the runner started and schedule a pod to execute the test because we are using dind service. But it is still started in the other nodes, and that is not what I expected.
The reason is that the created POD will not know the node_selector or node_tolearations, in the document link it is mentioned there, https://docs.gitlab.com/runner/executors/kubernetes.html
But because I am using the gitlab runner chart, so I won’t be able to set up the config.toml directly, I have to set it up them using the environment variable such as KUBERNETES_NODE_SELECTOR or KUBERNETES_NODE_TOLERATIONS. but those values are really a table type (map[string][string]), so how should I pass the string in the gitlab chart as environment variable?
I tried different ways but they are just ignored in the generated config.toml file when I added it in the _env_vars.tpl file such as
- name: KUBERNETES_NODE_SELECTOR
