Ansible failed_when条件不会阻止任务失败

Question

我正在运行以下ansible任务：

- name: Remove Jenkins
register: jenkins_delete
shell: "helm delete --purge --tls jenkins-{{ env_name }}"
retries: 2
delay: 20
until: jenkins_delete.rc == 0
failed_when: "'jenkins-{{ env_name }} not found' not in jenkins_delete.stderr"

如果我正在寻找的版本不存在，则失败如下：

fatal: [localhost]: FAILED! => {"attempts": 5, "changed": true, "cmd": "helm delete --purge --tls jenkins-inception", "delta": "0:00:00.212773", "end": "2020-01-24 13:58:24.993134", "failed_when_result": true, "msg": "non-zero return code", "rc": 1, "start": "2020-01-24 13:58:24.780361", "stderr": "Error: release: "jenkins-inception" not found", "stderr_lines": ["Error: release: "jenkins-inception" not found"], "stdout": "", "stdout_lines": []}

我正在使用的failed_when条件不应该阻止这种情况吗？

编辑：我也尝试过这个，但没有任何成功：

- name: Remove Jenkins
register: jenkins_delete
shell: "helm delete --purge --tls jenkins-{{ env_name }}"
retries: 2
delay: 10
until: jenkins_delete.rc == 0 or jenkins_delete.stderr is regex("release:.+not found")

这很奇怪，因为似乎使用的regex应该与stderr中的字符串匹配

据我所知，您的stderr中有引号jenkins-inception：

"Error: release: "jenkins-inception" not found".

此正则表达式应匹配：

"jenkins-{{ env_name }}" not found
