添加 Docker 安裝路徑

安裝必要的證書並允許 apt 包管理器使用以下命令通過HTTPS使用儲存庫:

$ sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release

添加 Docker 的官方 GCP 密鑰:

 $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

添加 Docker 官方安裝路徑:

$ echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

更新 Ubuntu:

$ sudo apt update
