Bug Report

kubectl v1.30.0 command failed in ansible-operator:v1.34.1 with error malformed ws or wss URL

What did you do?

We built our ansible operator image based on quay.io/operator-framework/ansible-operator:v1.34.1, and also put kubectl v1.30.0 into the operator image.
In one of ansible operator task, we need to use kubectl to copy some folder to temporary Operator pod, but this task failed with following error messages (some words are masked)
FAILED! => {"changed": true, "cmd": ["kubectl", "cp", "/some_path/some_folder", "{{tmp_operator_pod_name}}:/some_path", "-n", "name_space"], ..., "msg": "non-zero return code", "rc": 1, ..., "stderr": "Defaulted container "operator" out of: operator, **** (init)\nerror: malformed ws or wss URL", "stderr_lines": ["Defaulted container "operator" out of: operator, *** (init)", "error: malformed ws or wss URL"], "stdout": "", "stdout_lines": []}

- block:
  - name: Copy some folder from Operator to temporary Operator pod
    command: kubectl cp /some_path/some_folder {{tmp_operator_pod_name}}:/some_path -n {{meta.namespace}}

But the same task works with kubectl v1.29.3 or kubectl v1.28.0

What did you expect to see?

We expect the latest kubectl 1.30.* should work with ansible-operator:v1.34.1 or higher version to run "kubectl cp" or other kubectl commands.

What did you see instead? Under which circumstances?

"kubectl cp" command (kubectl v1.30.0) failed with error: malformed ws or wss URL

Not sure whether it is compatible problem for ansible-operator to invoke other go application (e.g. kubectl)?
kubectl v1.30.0 - goVersion: go1.22.2

kubectl v1.28.0 - goVersion: go1.20.7

Note that the command: kubectl cp could be rewritten with k8s_cp module (https://docs.ansible.com/ansible/latest/collections/kubernetes/core/k8s_cp_module.html) regardless of kubectl version.

[acornett21]

Hi @caixiangibm If you are adding in kubectl into the binary, it probably should match the k8's version that is supported with any ansible-operator release. Release 1.36.0 supports k8s 1.30, please re-try with this version. If you still have issues, it's probably best to implement what @PYLochou suggested instead of adding another binary to the container.
