如何在Jenkins容器化docker环境中运行liquibase docker映像

如何解决如何在Jenkins容器化docker环境中运行liquibase docker映像

我正在使用liquibase docker映像进行POC，

我想使用Jenkins kubernetes POD模板在docker中运行liquibase docker镜像。不幸的是无法实现。

我还附上了詹金斯文件和观察结果。

Jenkins文件

def workspace_dir = "/home/jenkins/agent/workspace/${env.JOB_BASE_NAME}"
def project_name = "master-chart"
def isDeployerJob = (env.JOB_BASE_NAME).contains("deploy") ? "true" : "false"

// These variables come from the build parameters in the Jenkins job
def git_branch = git_branch
def release_version


if (isDeployerJob == "true") {
    // Extracting the release version from the branch
    def temp = git_branch.split("/")
    release_version = temp[temp.length - 1]

    switch(environment) {
      case "dev":
        hs_jdbc_url="jdbc:postgresql://40.xx.xx.xx:5432/dbname"
        db_username="username"
        db_password="pwd"
        break
      default:
        break
    }
} 

pipeline {

  agent {
    kubernetes {
      cloud 'eks-tools-13'
      yaml """
apiVersion: v1
kind: Pod
spec:
  containers:
  - name: azcli-kubectl-helm
    image: internal.docker.cioxhealth.com/azcli-kubectl-helm
    command:

    image: docker
    command:

"""
    }
  }

  stages {
        
    stage('Install Database Scripts') {
      when {
        expression {
          "${isDeployerJob}" == "true"
        }
      }
      steps {
        container('docker') { 
            sh """
               docker run --rm --network="host" -v ${workspace_dir}/db:/liquibase/changelog liquibase/liquibase --url=${hs_jdbc_url} --changeLogFile=db.changelog-master.yaml --driver=org.postgresql.Driver --username=${db_username} --password=${db_password} --logLevel=info  update
            """
        }
      }
    }   
  
  }
}

为了验证文件，我进入了运行容器

Jenkins主节点： ls -ltr /home/jenkins/agent/workspace/master-chart-deploy/db

液体容器

docker run --rm '--network=host' -v /home/jenkins/agent/workspace/master-chart-deploy/db:/liquibase/changelog liquibase/liquibase -- ls -ltr /liquibase/changelog

正在运行的liquibase容器中没有文件。因此，发生了以下错误。

错误：

• 我可以知道，在这种情况下我做错了什么？以及为什么文件liquibase在运行容器中不可用？
• 这是一个问题，因为在Docker情况下，由于Docker导致的文件权限？
• 还有其他方法可以实现这一目标吗？

预先感谢您的帮助。

解决方法

我认为您在某种程度上搞砸了docker配置。从documentation看来，liquibase希望您将所有内容都安装在/liquibase/changelog目录中。

在您的命令中，您将更改日志映射到/app/liquibase：

docker run --rm --network="host" -v ${workspace_dir}/db:/app/liquibase liquibase/liquibase --url=${hs_jdbc_url} --changeLogFile=db.changelog-master.yaml --classpath=/app/liquibase --driver=org.postgresql.Driver --username=${db_username} --password=${db_password} --logLevel=info  update

所以我会使用它：

docker run --rm --network="host" -v ${workspace_dir}/db:/liquibase/changelog liquibase/liquibase --url=${hs_jdbc_url} --changeLogFile=db.changelog-master.yaml  --driver=org.postgresql.Driver --username=${db_username} --password=${db_password} --logLevel=info  update

注意：如果您依赖--classpath=/app/liquibase，或者添加了其他驱动程序或其他内容，则应该删除它border: InputBorder.none，但请先尝试阅读。我认为文档非常好。

在jekins管道中使用docker run时必须指定完整路径：

--changeLogFile=/app/liquibase/db.changelog-master.yaml 

在詹金斯管道中定义：

environment {
        HOME = '.'
    }
