使用容器名称而不是容器 ID 保存 docker 个容器日志
Saving docker container logs with container names instead of container IDs
使用默认的 json-file 日志记录驱动程序,是否可以使用容器名称而不是容器 ID 来记录轮换 docker 容器日志?
日志文件名中的容器 ID 看起来不太可读,这是我想用容器名称保存日志的时候吗?
可以使用日志选项配置引擎以在日志中包含标签:
# cat /etc/docker/daemon.json
{
"log-driver": "json-file",
"log-opts": {
"max-size": "10m",
"max-file": "3",
"labels": "com.docker.stack.namespace,com.docker.swarm.service.name,environment"
}
}
# docker run --label environment=dev busybox echo hello logs
hello logs
root@vm-11:/etc/docker# docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9615c898c2d2 busybox "echo hello logs" 8 seconds ago Exited (0) 7 seconds ago eloquent_germain
# docker logs --details 961
environment=dev hello logs
# more /var/lib/docker/containers/9615c898c2d2aa7439581e08c2e685f154e4bf2bb9fd5ded0c384da3242c6c9e/9615c898c2d2aa7439581e08c2e685f154e4bf2bb9fd5ded0c384da3242c6c9e-json.log
{"log":"hello logs\n","stream":"stdout","attrs":{"environment":"dev"},"time":"2020-09-22T11:12:41.279155826Z"}
您需要在对 daemon.json 进行更改后重新加载 docker 引擎,并且更改仅适用于新创建的容器。对于 systemd,重新加载是通过 systemctl reload docker
.
完成的
要专门传递不是标签的容器名称,您可以传递“标记”设置:
# docker run --name test-log-opts --log-opt tag="{{.Name}}/{{.ID}}" busybox echo hello log opts
hello log opts
# docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

# docker logs --details c20
