安裝完後輸入docker --version檢視版本。

[ec2-user@ip-172-31-14-20 ~]$ docker --version
Docker version 20.10.17, build 100c701


其他設定

輸入sudo usermod -a -G docker ec2-user把ec2-user使用者加到docker的user group,這樣之後執行docker命令前面就不用加sudo

[ec2-user@ip-172-31-14-20 ~]$ sudo usermod -a -G docker ec2-user

輸入newgrp docker重新載入docker user group設定。

[ec2-user@ip-172-31-14-20 ~]$ newgrp docker


啟動Docker服務

輸入sudo systemctl enable docker讓EC2每次重啟時會自動啟動docker服務。

[ec2-user@ip-172-31-14-20 ~]$ sudo systemctl enable docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

輸入sudo service docker start啟動docker服務。

[ec2-user@ip-172-31-14-20 ~]$ sudo service docker start
Redirecting to /bin/systemctl start docker.service

輸入docker info查看已安裝的docker的詳細資訊)。
