DOCKER

查看指定服务名的日志（只有一个服务实列）
docker service ps t_mserv_espare|grep Running|awk '{print $1}'|xargs docker service logs -f

构建镜像

docker build -t <TAG_NAME> <Dockerfile_PATH>

运行镜像

docker run -d -p 3000:3000/tcp -v /d:\\test:/home/test gettingg-started

-d(etach) 后台模式运行 -p(ublish) <hostPort>:<containerPort>/<protocol[tpc,udp...]> 端口映射

-v(olume) 磁盘映射 hostPath:containerPath

查看镜像列表

docker images

查看容器实例列表

docker ps 或者 docker container ls

查看实例中运行的程序的STD_OUT(标准输出)(eg:c语言中的print/printf,node:console.log,java:System.out…)

docker logs <containerId>

运行当前运行中容器中的命令

docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

Options:
  -d, --detach               Detached mode: run command in the background
      --detach-keys string   Override the key sequence for detaching a
                             container
  -e, --env list             Set environment variables
  -i, --interactive          Keep STDIN open even if not attached
      --privileged           Give extended privileges to the command
  -t, --tty                  Allocate a pseudo-TTY
  -u, --user string          Username or UID (format:
                             <name|uid>[:<group|gid>])
  -w, --workdir string       Working directory inside the container

eg: docker exec -it 12e /bin/sh

执行上述命令后会会自动连接到目标容易的终端

删除容器

`docker rm -f

创建服务

docker service create [OPTIONS] IMAGE [COMMAND] [ARG...]

强制重启服务

docker service update your_service_name --force

查看service的containerId

for f in $(docker service ps -q t_mserv_base_mq);do docker inspect --format '{{.ServiceID}} {{.NodeID}} {{.Status.ContainerStatus.ContainerID}} {{.DesiredState}}' $f; done

docker 容器可视化

docker pull dockersamples/visualizer:latest
docker service create \
--name=viz \
--publish=12306:8080/tcp \
--constraint=node.role==manager \
--mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
dockersamples/visualizer:latest

DockerFile

COPY SRC DEST

复制src文件到dest

ADD SRC DEST

复制src文件到dest,如果src为压缩文件，怎复制和自动解压

CMD cmd args…

在docker run 时运行

RUN cmd args…

在docker build时运行，可能

HEX(NUM) -> DECIMAL
int r= (int)(NUM / 10)*16 + NUM%10

日志

docker service logs --help

Usage:  docker service logs [OPTIONS] SERVICE|TASK

Fetch the logs of a service or task

Options:
      --details        Show extra details provided to logs
  -f, --follow         Follow log output
      --no-resolve     Do not map IDs to Names in output
      --no-task-ids    Do not include task IDs in output
      --no-trunc       Do not truncate output
      --raw            Do not neatly format logs
      --since string   Show logs since timestamp (e.g. 2013-01-02T13:23:37Z) or relative (e.g. 42m for 42 minutes)
  -n, --tail string    Number of lines to show from the end of the logs (default "all")
  -t, --timestamps     Show timestamps

eg：

查询日志通过服务名

docker service logs t_mserv_xgb_project --since 2022-04-22

查询日志通过taskId

获取服务对应的taskId

docker service ps t_mserv_xgb_project

通过taskId获取日志输出

docker service logs taskId --since 2022-04-22
