Install the docker in fast time
These are the dependencies that will be needed to install the docker
To start clone the repository:
git clone https://github.com/Kledenai/docker-installation.git
This is a more automatic way to install the docker, running this code in your server.
sudo ./install.sh
obs: you have to be inside the root folder of that repository.
After the script finishes running everything it needs, run the following command to check if the docker is installed correctly.
sudo docker version
This is the manual form, there are a few more steps, but you can check each step by step and better understand what is happening
if you have an old docker installation run the following command
sudo apt-get -y remove docker docker-engine docker-cli docker-ce-cli docker.io
in case you have already installed the docker with the snap on your machine, run the following command:
sudo snap remove docker
Update all linux packages
sudo apt-get update
start docker installation
sudo apt-get -y install docker.io
Start docker service in the machine
sudo systemctl start docker
Now enable the docker on the server
sudo systemctl enable docker
Need to increase the value of the map count, run this command below
sudo sysctl -w vm.max_map_count=262144
if everything went well, run the command below to verify that both the client and the docker engine are installed
sudo docker version
It is very common for some errors to occur during installation
Having said that, I went through these errors which I will list here and will pass the solution on to them below
docker.io : Depends: containerd (>= 1.2.6-0ubuntu1~)E: Unable to correct problems, you have held broken packages.
sudo apt-get remove containerd.io
Failed to start docker.service: Unit docker.service is masked.
sudo systemctl unmask docker
