App 自動化測試（二）Docker 安裝與使用

前言

Docker 安裝

sudo apt-get remove docker docker-engine docker.io containerd runc

sudo apt-get update
sudo apt-get install \
    ca-certificates \
    curl \
    gnupg

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

sudo docker run hello-world
...
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:

Docker 基本操作

察看容器運作狀態

sudo docker ps

全部顯示容器包含停止狀態的，就加 -a

sudo docker ps -a

容器的狀態與管理

獲得容器ID

$ sudo docker ps
CONTAINER ID   IMAGE                           COMMAND                  CREATED        STATUS        PORTS                                       NAMES
b964347efaf9   redroid/redroid:11.0.0-latest   "/init qemu=1 androi…"   13 hours ago   Up 12 hours   0.0.0.0:5555->5555/tcp, :::5555->5555/tcp   redroid11

啟動停止重啟容器

sudo docker start [容器ID]

sudo docker stop [容器ID]

sudo docker restart [容器ID]

sudo docker rename [容器ID] [容器新名字]

清除容器服務的資料

sudo docker system df

sudo docker system df -v

sudo docker system prune -a

sudo docker system prune
