Vậy là bạn đã cài xong docker rồi giờ chúng ta hãy test việc sử dụng docker:
Tạo nhóm docker:
sudo groupadd docker
Thêm user vào nhóm docker :
sudo usermod -aG docker $USER
Nhớ thay $USER bằng tên user của bạn nhé
Kiểm tra phiên bản docker:
docker --version
Kết quả trả về như sau
root@phuong:~# docker --version
Docker version 24.0.7, build 24.0.7-0ubuntu2~22.04.1
Thử sử dụng docker với hello-world container:
docker run hello-world
Kết quả trả về như sau:
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
