图像未拉入 systemd ExecStartPre=

Question

我从 systemd/dockerd 收到这条消息：

Dec 29 14:41:32 core-01 systemd[1]: Starting ElasticSearch...
Dec 29 14:41:32 core-01 docker[1335]: Error response from daemon: No such container: es
Dec 29 14:41:32 core-01 docker[1346]: Error response from daemon: No such container: es
Dec 29 14:41:33 core-01 docker[1367]: Pulling repository prv.private.registry/elasticsearch-qa
Dec 29 14:41:33 core-01 docker[1367]: Error: image elasticsearch-qa not found
Dec 29 14:41:33 core-01 systemd[1]: living-es.service: Control process exited, code=exited status=1

所以它告诉我 image elasticsearch-qa not found。

systemd 服务定义为：

  - name: living-es.service
    command: start
    enable: true
    content: |-
      [Unit]
      Description=ElasticSearch
      Author=Living
      After=docker.service

      [Service]
      Restart=always
      RestartSec=10s
      ExecStartPre=-/usr/bin/docker stop es
      ExecStartPre=-/usr/bin/docker rm es
      ExecStartPre=/usr/bin/docker pull prv.private.registry/elasticsearch-qa:v1
      ExecStart=/usr/bin/docker run --name es -p 9200:9200 -p 9300:9300 --hostname es -v /home/core/data/es:/usr/share/elasticsearch/data prv.private.registry.com/elasticsearch-qa:v1 -Des.node.name="esn1" -Des.cluster.name="cluster"
      ExecStop=/usr/bin/docker stop es

消息很清楚，但是，当我在 shell 上拉取图像时，它被正确拉取了。有什么想法吗？

Answer 1

尝试运行以 root 的身份手动执行 docker pull 命令，因为那是 systemd 运行的用户。它可能无法验证您的私人存储库，因为凭据存储在您的用户首选项中。

如果是这样，请尝试将 User=yourusername 添加到您的 systemd 单元文件中。
