Question

我正在使用docker来测试我的剧本。

我现在创建了一个容器，当我在容器内运行命令时，它给我下面的错误

ansible-playbook jenkins.yml

错误： -

[root@db1e9105692d jenkins-playbook]# ansible-playbook  jenkins.yml -k -vvv
SSH password:

PLAY [localhost] **************************************************************

It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

TASK: [jenkins | Include OS-Specific variables] *******************************

FATAL: all hosts have already failed -- aborting

localhost                  : ok=0    changed=0    unreachable=2    failed=0

但是，如果我在主机上运行此命令，它运行正常。我需要做任何事情，以便连接不会被拒绝在端口22.inside docker container

请不要将下面的行视为错误的原因。只是ansible在抛出错误之前已经执行了几行。实际上它无法运行，因此该变量的值为空。

fatal: [localhost] => One or more undefined variables: 'ansible_os_family' is undefined

Answer 1

在你的容器中在本地启动你的剧本：

$ ansible-playbook jenkins.yml -c local -k -vvv

Answer 2

您是否为localhost定义了connection=local？它试图通过ssh进行连接，因为您可能没有在容器中运行sshd，因此无法正常工作。

如何在docker容器中运行ansible脚本
