How to Install Docker on Linux Mint 20.

Hi hope you are doing well, lets learn about “How to Setup and Install Docker on Linux Mint 20”, the Docker is the fastest growing technology in the IT market. Docker is the container technology.

Many industries are moving towards docker from the normal EC2 instances. It is PAAS (Platform as a Service), which uses a OS virtualisation to deliver software in packages called containers.

The containers are the bundle of the packages, library files, and some configuration files. It was first started in 2013 and developed by Docker, Inc.

So lets have the Setup of Docker CE on Linux Mint 20. Step by Step Guide.


Setup and Install Docker CE on Linux Mint 20

STEP 1: Update the Repository for the Docker to setup and Install on Linux Mint 20.

So firstly we will update the repository and install some of packages with the apt command.

$ sudo apt update

Let’s add the Docker’s official GPG key:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(. /etc/os-release; echo "$UBUNTU_CODENAME") stable"
$ sudo apt update

Now update the repository for the docker and Install Docker on Linux Mint 20.


STEP 2: Setup and Install Docker CE on Linux Mint 20 via apt command.

So, install docker-ce, docker-ce-cli and container.io packages in Linux Mint.

$ sudo apt-get -y install docker-ce docker-ce-cli containerd.io
apt install for Docker CE.

Once the docker installation get’s completed , check the status of services for the docker and enable it after rebooting the System.

$ sudo systemctl status  docker.service
Install Docker on Rocky Linux 8
Check the Docker Status

So we have check the status for docker, and it is active running on the Linux Mint 20, so enable the service for docker at the time of booting.

$ sudo systemctl enable docker.service

STEP 3: Add the User in Docker Group.

Now lets add user “tastethelinux” into the docker group.

$ sudo usermod -aG docker $USER

“$USER” is the username tastethelinux, you can use whoami to check the username.

docker --version
OUTPUT:
Docker version 20.10.8, build 3967b7d

So then check version using docker command without sudo, you will get the version for the docker.

Let’s check the installation with the docker info command, which gives the information about the Docker.

$ docker info
docker info

So we have successfully install Docker CE on Linux Mint 20, lets create a Container for the MongoDB.


STEP 4: Test Docker by Pulling Images.

So here we will create a container for MongoDB on docker, let’s use the pull command to pull the MongoDB image first.

Install Docker on Rocky Linux 8
docker pull image_name
$ docker pull mongo

So we have pulled the images for mongo from the docker, Once it’s completed you can check the image by using “docker images”.

$ docker images

STEP 5: Run Docker Container in Linux Mint 20.

Now let’s run the docker container by using docker run command.

$ docker run -d mongo

So we have successfully run the docker container in Linux Mint 20 for MongoDB, now if we have to verify the container is running or not use “docker ps” command.

$ docker ps 

Run the container for MongoDB server on Linux Mint 20.
