尝试连接到ansible

中的主机时出错

我可以在本地主机（ansible）中ping ssh_connection，但不能在jenkins管道构建中ping。

我几乎尝试过所有事情。

你可以帮我解决这个问题......

Answer 1

在您的ansible配置文件[defaults] host_key_checking = False中添加以下行并再次测试。

memory.size()

Answer 2

在ansible中禁用主机密钥检查的另一种方法是将ANSIBLE_HOST_KEY_CHECKING环境变量设置为False

export ANSIBLE_HOST_KEY_CHECKING=False

Ansible Docs

Answer 3

机器首次连接后是否重建了？

如果需要，您需要从~/.ssh/known_hosts中删除主机，或将以下选项添加到SSH：StrictHostKeyChecking=no。

Answer 4

您可以使用Jenkins ansible插件执行此操作。他们的文档中的主机密钥检查有错误，但是here is a full working example：

以下是该决议的重要摘要：

ansiColor('xterm') {
    ansiblePlaybook(
        playbook: './ansible/playbook.yml',
        inventory: '/tmp/inventory.ini',
        credentialsId: 'your-jenkins-pk-credential',
        disableHostKeyChecking: true,
        colorized: true)
    }
}

无法通过ssh连接到主机：主机密钥验证失败。\ r \ n
