¶ Use of docker
The default system image source is Tsinghua source, and other sources can also be used, such as Alibaba Cloud, Huawei Cloud, etc. The system source file of Ubuntu is located in /etc/apt/sources.list. You can modify this file to add a mirror source. Please make sure to back it up before modifying it.
- Update apt index packages
sudo apt update
- If you have installed docker before, you need to first remove the possible old version.
apt remove docker docker-engine docker-ce docker.io
- Install the packages required to add new repositories over HTTPS
apt install -y apt-transport-https ca-certificates curl software-properties-common
Press Enter to keep the current download version
4. Use the following curl command to import the GPG key of the Docker official repository:
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
Upon success, the command returns OK.
- Add the Docker Alibaba Cloud image source to the Ubuntu system’s software source list:
add-apt-repository "deb [arch=arm64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu
$(lsb_release -cs) stable"
Press Enter to continue execution
6. Update apt package index again
apt update
7. Install the latest version of Docker CE
apt install docker-ce
Press Enter to keep the current download version
8. After the installation is complete, the Docker service will start automatically. To verify it type:
systemctl status docker
Found that starting docker failed
Enter dockerd to view logs and troubleshoot problems
dockerd
Press ctrl+c to exit error
9. Ubuntu 22.04 uses nftables as the firewall by default instead of iptables. Enter the following commands to resolve
sudo update-alternatives --set iptables /usr/sbin/iptables-legacy
10. Restart docker and check docker status
systemctl restart docker
systemctl status docker
11. Enter the command, and the following picture will appear, indicating that docker is installed successfully:
