我什么时候运行Docker镜像？

Question

我想知道何时启动了特定的Docker镜像。我可以用docker images查看图像。但是使用docker ps -a没有列出图像，因为我们使用--rm选项运行图像，因此，容器将在它们结束后立即被删除。

是否有某种日志可以判断特定图像何时运行？

我试过docker inspect，但它不包含我需要的信息。此外，/var/log/docker.log也没有帮助我。

Answer 1

最好这样想一想：

1. 你没有run图像，但是
2. 你基于图像的run容器。

所以，使用：docker container inspect <your_container_name>你会得到很多信息，例如：

[
    {
        "Id": "4b9fdc1aa126c24461bfc1309517c0394da7b67af4b92aaedb5d635deb7d4561",
        "Created": "2017-12-19T12:36:56.038085061Z",
        "Path": "/run.sh",
        "Args": [],
        "State": {
            "Status": "running",
            "Running": true,
            "Paused": false,
            "Restarting": false,
            "OOMKilled": false,
            "Dead": false,
            "Pid": 5171,
            "ExitCode": 0,
            "Error": "",
            "StartedAt": "2017-12-20T11:05:50.753491979Z",
            "FinishedAt": "2017-12-19T16:49:28.78225137Z"
        },
...

我相信你会寻找：

• Created：通过运行docker run ...或者创建容器的时候
• StartedAt：这是通过运行docker container start ...启动容器的时候（如果有一个started以前是stopped的容器，可能会使用这个）

您可以使用docker ps命令轻松查看STATUS和正常运行时间。

查找STATUS和CREATED列。

$ docker ps

CONTAINER ID    IMAGE       COMMAND   CREATED        STATUS         PORTS               NAMES
7ccd6b46a2e9    httpd:2.4   "httpd"   7 minutes ago  Up 7 minutes   0.0.0.0:80->80/tcp      its-apache

Answer 3

命令docker ps --filter ancestor=xxx做你想要的

见文档

例

$ docker ps

如果我只想要运行图像k3ck3c / apt_cacher的容器

$ docker ps --filter ancestor=k3ck3c/apt_cacher
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

$ 

或图像k3ck3c/captvty

$ docker ps --filter ancestor=k3ck3c/captvty
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
