我什么时候运行Docker镜像？

我想知道一个特定的Docker镜像何时启动。 我可以用docker images查找docker images 。 但图像没有使用--rm docker ps -a列出，因为我们使用--rm选项运行图像，因此，容器将在结束后立即被删除。

有什么样的日志可以告诉特定的图像已经运行？

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

Answer 1

最好这样想：

1. 你不run 图像 ，但
2. 你基于图像 run 容器 。

所以，通过： docker container inspect <your_container_name>您可以获得许多信息，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" }, ... 

我相信你在寻找：

• Created ：这是通过运行docker run ...创build容器docker run ...或

• StartedAt ：通过运行docker container start ... （如果已经started了一个先前已经stopped的容器，可能会使用这个）

Answer 2

您可以使用docker ps命令轻松查看状态和正常运行时间。

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做你要找的东西

看文档

https://docs.docker.com/engine/reference/commandline/ps/

例

如果我只想运行映像k3ck3c / apt_cacher的容器

 $ docker ps --filter ancestor=k3ck3c/apt_cacher CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 11b4606ccad2 k3ck3c/apt_cacher "/bin/sh -c 'chmod..." 6 weeks ago Up 58 seconds 0.0.0.0:3142->3142/tcp test_apt_cacher_ng $ 

或图像k3ck3c/captvty

 $ docker ps --filter ancestor=k3ck3c/captvty CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES bc07fd1d98a9 k3ck3c/captvty "/bin/sh -c 'WINED..." 5 days ago Up 5 minutes gallant_stallman e06b854ce5ad k3ck3c/captvty "/bin/sh -c 'WINED..." 9 days ago Up 5 minutes quirky_mclean 2070187bf6d2 k3ck3c/captvty "/bin/sh -c 'WINED..." 2 weeks ago Up 4 minutes vibrant_agnesi 37e30ba9c5cf k3ck3c/captvty "/bin/sh -c 'WINED..." 2 weeks ago Up 4 minutes naughty_boyd d5f57a41bd0b k3ck3c/captvty "/bin/sh -c 'WINED..." 2 weeks ago Up 4 minutes musing_mahavira $
