从 jenkins 运行 ansible-playbook 时，如何修复“KeyError: 'getpwuid(): uid not found: 1000'”

Question

我有这个 jenkins 管道，用于执行ansible-playbook 。

pipeline {
    agent {
        docker {
            image 'gableroux/ansible'
            args '-i --entrypoint='
        }
    }
    stages {
        stage('Setup parameters') {
            steps {
                script {
                    properties([
                        parameters([
                            string( defaultValue: 'hosts', name: 'INVENTORY', trim: true ),
                            string( defaultValue: '\'*\'', name: 'LIMIT', trim: true ),
                            string( defaultValue: 'shell', name: 'PLAYBOOK', trim: true ),
                            string( defaultValue: '--list-hosts', name: 'EXTRA_PARAMS', trim: true )
                        ])
                    ])
                }
            }
        }
        stage('Execute Ansible Playbook.') {
            steps {
                script {
                    env.DEFAULT_LOCAL_TMP = env.WORKSPACE_TMP
                    env.HOME = env.WORKSPACE

                    sh """
                    ansible-playbook -i ${INVENTORY} -l "${LIMIT}" ${PLAYBOOK} ${EXTRA_PARAMS}
                    """
                }
            }
        }
    }
}

我将这些参数传递给它：

INVENTORY -> ",localhost"
LIMIT -> ' '
PLAYBOOK -> 'the_playbook.yml'
EXTRA_PARAMS -> -vvv --connection=local --user root

the_playbook.yml的内容是：

---
  - name: "Playing with Ansible and Git"
    hosts: localhost
    connection: local
    tasks:

    - name: "just execute a ls -lrt command"
      shell: "ls -lrt"
      register: "output"

    - debug: var=output.stdout_lines

当我的管道运行时，我收到以下错误消息：

+ ansible-playbook -i ,localhost -l ' ' the_playbook.yml -vvv '--connection=local' --user root

我能做些什么来修复它？

Answer 1

试试下面的。

sh '''
echo "tempuser:x:$(id -u):$(id -g):,,,:${HOME}:/bin/bash" >> /etc/passwd
echo "tempuser:x:$(id -G | cut -d' ' -f 2)" >> /etc/group
'''
sh """
ansible-playbook -i ${INVENTORY} -l "${LIMIT}" ${PLAYBOOK} ${EXTRA_PARAMS}
"""

或者您可以尝试在基础映像中创建一个 UID 为 1000 的用户。 请参阅此以获取更多信息。
