使用容器内的结构部署应用程序

Question

我正在使用 Jenkins 设置，其中每个从站都是一个临时 docker 容器，Jenkins 用户通过 ssh 连接连接到容器/从站。在 Jenkins 流水线结束时，如果所有测试和分析都正常，则使用结构脚本将应用部署到暂存环境。

Fab 文件：

@task
def deploy():
    require('context', provided_by=(stage,prod,pprod))

    #figure out the package and file names and version
    file_name = [f for f in os.listdir(".") if fnmatch.fnmatch(f, '*.tar.gz')][0]
    package_name = file_name.split('.')[0]#os.path.splitext(fullname)[0]

    setup_ssh_agent()

    # upload the package to the temporary folder on the server
    with cd(env.release_dir):
      put('{}'.format(file_name), '.')   

def setup_ssh_agent():
  local('eval "$(ssh-agent -s)" && ssh-add /home/jenkins/.ssh/id_rsa')

我收到此错误：

ssh 身份在登台服务器上获得授权，我已经在我的 Linux 电脑上使用该身份测试了与该机器的 ssh 连接并且它可以工作，我必须使用该 ssh 密钥从我的机器运行该脚本并且它也可以工作.

如果有人遇到过这个问题，我很想知道您是如何解决的。 提前致谢。

检查你要部署的服务器是否有 jenkins 用户 ssh 密钥。

看起来函数 setup_ssh_agent() 没有完成它的工作 jenkins 用户没有 .ssh/id_rsa .ssh/id_rsa/pub 文件的可能原因

那么您必须在本地计算机上为用户 jenkins 创建它们

sudo su jenkins

cd

mkdir .ssh

cd .ssh

ssh-keygen -t rsa

将 id_rsa.pub 复制到 ~/.ssh/authorized_keys 到目标服务器
