Set up the repository
\nUpdate the apt package index and install packages to allow apt to use a repository over HTTPS:<\/p>\n

\n$ sudo apt-get update\n<\/pre>\n
\n$ sudo apt-get install ca-certificates curl gnupg lsb-release\n<\/pre>\n
Add Docker\u2019s official GPG key:<\/p>\n
\n$ curl -fsSL https:\/\/download.docker.com\/linux\/debian\/gpg | sudo gpg --dearmor -o \/usr\/share\/keyrings\/docker-archive-keyring.gpg\n<\/pre>\n
Use the following command to set up the stable repository.<\/p>\n
\necho \\\n "deb [arch=$(dpkg --print-architecture) signed-by=\/usr\/share\/keyrings\/docker-archive-keyring.gpg] https:\/\/download.docker.com\/linux\/debian \\\n  $(lsb_release -cs) stable" | sudo tee \/etc\/apt\/sources.list.d\/docker.list > \/dev\/null\n<\/pre>\n
Install Docker Engine<\/p>\n
Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:<\/p>\n
\n$ sudo apt-get update\n$ sudo apt-get install docker-ce docker-ce-cli containerd.io\n<\/pre>\n
Verify that Docker Engine is installed correctly by running the hello-world image.<\/p>\n
\n$ sudo docker run hello-world\n<\/pre>\n
Configure Docker to start on boot<\/p>\n
\n$ sudo systemctl enable docker.service\n$ sudo systemctl enable containerd.service\n<\/pre>\n
Manage Docker as a non-root user
\nCreate the docker group.<\/p>\n
\nsudo groupadd docker\n<\/pre>\n
Add your user to the docker group.<\/p>\n
\nsudo usermod -aG docker $USER\n<\/pre>\n
Log out and log back in so that your group membership is re-evaluated. If testing on a virtual machine, it may be necessary to restart the virtual machine for changes to take effect. On a desktop Linux environment such as X Windows, log out of your session completely and then log back in.<\/p>\n
On Linux, you can also run the following command to activate the changes to groups:<\/p>\n
\nnewgrp docker \n<\/pre>\n
Verify that you can run docker commands without sudo.<\/p>\n
\n$ docker run hello-world\n<\/pre>\n
This command downloads a test image and runs it in a container. When the container runs, it prints a message and exits.<\/p>\n
Configuring remote access with systemd unit file<\/p>\n
Use the command sudo systemctl edit docker.service to open an override file for docker.service in a text editor. Add or modify the following lines, substituting your own values.<\/p>\n
\n[Service]\nExecStart=\nExecStart=\/usr\/bin\/dockerd -H fd:\/\/ -H tcp:\/\/127.0.0.1:2375\n<\/pre>\n
Save the file. Reload the systemctl configuration.<\/p>\n
\n sudo systemctl daemon-reload\n<\/pre>\n
Restart Docker.<\/p>\n
\n sudo systemctl restart docker.service\n<\/pre>\n
Check to see whether the change was honored by reviewing the output of netstat to confirm dockerd is listening on the configured port.<\/p>\n
\n$ sudo netstat -lntp | grep dockerd\n<\/pre>\n
Configuring remote access with daemon.json<\/p>\n
    Set the hosts array in the \/etc\/docker\/daemon.json to connect to the UNIX socket and an IP address, as follows:<\/p>\n
\n    {\n      "hosts": ["unix:\/\/\/var\/run\/docker.sock", "tcp:\/\/127.0.0.1:2375"]\n    }\n<\/pre>\n
Restart Docker. Check to see whether the change was honored by reviewing the output of netstat to confirm dockerd is listening on the configured port.<\/p>\n
\n sudo netstat -lntp | grep dockerd\n<\/pre>\n
