For the purpose of this tutorial, I am using a virtual machine running on EXSI 5.5 host. The VM has 2GB of memory, 1 CPU and 60GB of disk. I named the VM Docker2001.The VM is in a DHCP and DNS environment with a docker2001.dfw.ppnet as the FQDN. If you have a bare metal, you can use that also. The VM has Debian Stretch installed on it.
Login to your server, create a file called docker_install.sh. Copy and paste the script below into the file.
#!/bin/bash sudo apt-get -y install curl curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add - sudo apt-get -y install software-properties-common sudo apt-get -y install apt-transport-https sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable" sudo apt-get update apt-cache policy docker-ce sudo apt-get install -y docker-ce
Save the file and make the file executable and run the script.
sudo chmod +X docker_install.sh sudo ./docker_install.sh
Check the installation by checking the docker version
ppaul@docker2001:~$ sudo docker --version Docker version 18.06.1-ce, build e68fc7a
Working with images
The first command we are going to us, is the command to list all our images.
ppaul@docker2001:~$ sudo docker images REPOSITORY TAG IMAGE ID CREATED
We can see that for now we have no images.
The command to download an images is
docker pull "name_of_images
We are going to download the percona monitoring image
docker pull percona/pmm-server:latest
ppaul@docker2001:~$ sudo docker images REPOSITORY TAG IMAGE ID CREATED SIZE percona/pmm-server latest deac61541b67 5 weeks ago 1.08GB
Now we can see that we have an image.
