Continuous integration 如何在Gitlab CI脚本中删除符号链接的目标？

我在设置

.gitlab ci.yml

文件时遇到问题。我想删除旧的提交，因此在（Debian）服务器上只有最新和以前的提交可用

由于某些原因，当脚本执行时，它的行为与预期不符-提交被正确切换，但旧的提交会保留在文件夹中，并且不会使用

rm-rf$（readlink）

但是，如果我使用同一用户在服务器上使用SSH并执行完全相同的步骤，

rm-rf$（readlink）

成功删除实际的符号链接目标（预期行为）。从CI脚本执行相同操作时，不会删除目标

也许我错过了一些变量转义，或者括号

这是我的（修剪过的）

.gitlab ci.yml

文件：

variables:
    SSH_USER: "user@server"
    PROJECT_DIR: "/domains/example.com/project-name"
    DEPLOY_DIR: "${PROJECT_DIR}/deploy"
    STAGING_TEMP_DIR: "${PROJECT_DIR}/staging-temp"
    # is this correct?
    DELETE_STAGING_TEMP: "'$$(readlink -f ${STAGING_TEMP_DIR})'"

stages:
    - build
    - deploy
    - post-deploy

Post Deploy staging:
    stage: post-deploy
    script:
        # switch last version
        - ssh $SSH_USER mv ${PROJECT_DIR}/staging-previous ${STAGING_TEMP_DIR} || true
        - ssh $SSH_USER mv ${PROJECT_DIR}/staging-latest ${PROJECT_DIR}/staging-previous || true
        - ssh $SSH_USER rm -rf ${DELETE_STAGING_TEMP}
        - ssh $SSH_USER unlink ${STAGING_TEMP_DIR} || true
        - ssh $SSH_USER ln -s ${DEPLOY_DIR}/${CI_COMMIT_REF_NAME}/${CI_COMMIT_SHA} ${PROJECT_DIR}/staging-latest

我也试过这个变体：

variables:
    SSH_USER: "user@server"
    PROJECT_DIR: "/domains/example.com/project-name"
    DEPLOY_DIR: "${PROJECT_DIR}/deploy"
    STAGING_TEMP_DIR: "${PROJECT_DIR}/staging-temp"

Post Deploy staging:
    stage: post-deploy
    script:            
        # switch last version
        - ssh $SSH_USER mv ${PROJECT_DIR}/staging-previous ${STAGING_TEMP_DIR} || true
        - ssh $SSH_USER mv ${PROJECT_DIR}/staging-latest ${PROJECT_DIR}/staging-previous || true      
        # is this correct? 
        - ssh $SSH_USER rm -rf "$(readlink -f ${STAGING_TEMP_DIR})"
        - ssh $SSH_USER unlink ${STAGING_TEMP_DIR} || true
        - ssh $SSH_USER ln -s ${DEPLOY_DIR}/${CI_COMMIT_REF_NAME}/${CI_COMMIT_SHA} ${PROJECT_DIR}/staging-latest

请注意：

${PROJECT\u DIR}/staging previous

和

${PROJECT\u DIR}/staging latest

是提交的符号链接

有人有类似的问题吗？或者您是否使用其他方法来删除旧的（不再需要的）提交？

最终找到了一个解决方案-回退转义很糟糕`

Post Deploy STAGING:
    stage: post-deploy
    script:
        # checks if current commit is already set up as staging-latest
        # if not, then this is new release, so switch last version:
        # - move staging-previous to temp
        # - move staging-latest to staging-previous
        # - delete the content of temp dir and unlink temp
        - >
            ssh $SSH_USER "if [ \"\`readlink ${PROJECT_DIR}/staging-latest\`\" != \"${DEPLOY_DIR}/${CI_COMMIT_REF_NAME}/${CI_COMMIT_SHA}\" ];
            then \`mv ${PROJECT_DIR}/staging-previous ${STAGING_TEMP_DIR} || true;
            mv ${PROJECT_DIR}/staging-latest ${PROJECT_DIR}/staging-previous || true\`;
            rm -rf \`readlink -f ${STAGING_TEMP_DIR}\`;
            unlink ${STAGING_TEMP_DIR} || true;
            fi;"
        - ssh $SSH_USER ln -s ${DEPLOY_DIR}/${CI_COMMIT_REF_NAME}/${CI_COMMIT_SHA} ${PROJECT_DIR}/staging-latest || true

终于找到了一个解决方案——这是一个糟糕的回跳逃逸`

    stage: post-deploy

        # if not, then this is new release, so switch last version:
        # - move staging-previous to temp
        # - move staging-latest to staging-previous
        # - delete the content of temp dir and unlink temp
        - >
            ssh $SSH_USER "if [ \"\`readlink ${PROJECT_DIR}/staging-latest\`\" != \"${DEPLOY_DIR}/${CI_COMMIT_REF_NAME}/${CI_COMMIT_SHA}\" ];
            then \`mv ${PROJECT_DIR}/staging-previous ${STAGING_TEMP_DIR} || true;
            mv ${PROJECT_DIR}/staging-latest ${PROJECT_DIR}/staging-previous || true\`;
            rm -rf \`readlink -f ${STAGING_TEMP_DIR}\`;
            unlink ${STAGING_TEMP_DIR} || true;
            fi;"
        - ssh $SSH_USER ln -s ${DEPLOY_DIR}/${CI_COMMIT_REF_NAME}/${CI_COMMIT_SHA} ${PROJECT_DIR}/staging-latest || true
