docker-安裝相關服務

00 安裝需求

CPU指令集支緩:
- 虛擬化支援(VT-X & VT-D)
- 64bit CPU+OS
  - X86: Intel(EM64T)&AMD(amd64)
  - ARM: armv8之後(AArch64)
RAM: 至少4GB以上
OS
- Linux: Kernel 3.8以上
- macOS: 10.14 以後
- Windows: 10/Server 2016以上 + Hyper-V支援

01 安裝&設定

1-1 Linux

01 安裝套件包

使用Linux發行版套件庫的版本
- fedora/RHEL like: $ sudo dnf install -y docker
- arch: $ sudo pacman -S docker
- debian: $ sudo apt install docker.io
使用官方套件庫的版本
- fedora/RHEL like
  - 加入&啟用來源套件庫: $ sudo dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
  - 開始安裝: $ sudo dnf -y install docker-ce docker-ce-cli containerd.io docker-compose-plugin

02 開機自動啟用docker

$ sudo systemctl enable --now docker.socket

03 提高當前使用者的權限,讓非root帳戶來使用Docker

$ sudo gpasswd -a $USER docker
$ sudo newgrp docker
$ sudo chmod 666 /var/run/docker.sock

1-2 Mac&Windows

由於macOS和Windows的內核架構不同，則有對應不同的解法。

安裝一台VM(ex: Ubuntu/Debian)，在其VM上安裝docker
- VMware
- QEMU
- VirtualBox
- Hyper-V
  - WSL2
使用Docker Desktop
- Windows
- macOS
