Dockerfile构建速度过慢，更换国内源方法 (apt / pip)

apt方法：

       在Dockerfile中添加如下两句代码：

RUN  sed -i s@/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list

RUN  apt-get clean

* /archive.ubuntu.com/        ->        /原本的地址（可以在/etc/apt/sources.list中查看）/

pip方法：

        在Dockerfile中添加：

RUN pip install -U pip

RUN pip config set global.index-url http://mirrors.aliyun.com/pypi/simple

RUN pip config set install.trusted-host mirrors.aliyun.com

or

RUN pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn -r requirements.txt

How to build your own docker

 1. Dockerfile:

Some commands for docker

install docker:

curl -fsSL https://test.docker.com -o test-docker.sh sudo sh test-docker.sh

1. list the containers: docker ps
2. list all the containers: docker ps -a
3. list the images: docker images
4. change another image name: docker tag name1 name2
5. commit the change to image: docker commit id name
6. delete the image: docker rmi name
7. stop a container: docker stop name
8. remove a container: docker rm name

• enter into a container: 

docker exec -it Name /bin/bash

• save a image:

docker save image_name > Name.tar

• load a image:

docker load < Name.tar

• start a docker:

docker run --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864
--cap-add SYS_PTRACE --rm --gpus all --pid=host --net=host
--security-opt apparmor:unconfined  -e DISPLAY=$DISPLAY
-v /home/temp:/workspace -v /home/pipeline:/data/pipeline
-w /data/pipeline_capture -it Name

9. docker compose:

    start all the images:

        docker-compose up -d

        docker-compose up -d --build

        docker-compose -f docker-compose-local.yml -d --build

        (use a specific docker compose file)

    stop all the images:

        docker compose down

10. docker storage analysis:

    docker system df

11. docker clear storage:

    clean all:

        docker system prune

    clean cache:

        docker builder prune

    clean volume:

        docker volume prune

    clean container:

        docker container prune

12. docker logs:

    if i only want to check the last 100 lines of logs since a certain time:

        docker logs -f -t [--since="2018-02-08"] --tail=100 CONTAINER_ID

            -f: 跟踪实时日志

            -t: 显示时间戳

 

    if i only want to check the latest 30min of logs:

        docker logs --since 30m CONTAINER_ID
