Set up Docker and Portainer

In first part we securely set up virtual machine and install nginx with https support by Let’s Encrypt certbot. In this second part we setup Docker and Portainer. Portainer we will use for docker comfortable control. Let’s start!

Install docker

You need to prepare your virtual machine to install docker - set up the Docker repository.

Set up the repository

First you need to update apt index and install some dependencies, which needed for docker install. Update the apt package index:

sudo apt-get update && \
    apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \

Next add Docker’s GPG key from

curl -fsSL | sudo apt-key add -

You could verify your received key with the fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88:

sudo apt-key fingerprint 0EBFCD88

pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <>
sub   rsa4096 2017-02-22 [S]

Finally, add repository to your system:

sudo add-apt-repository \
   "deb [arch=amd64] \
   $(lsb_release -cs) \

Install docker

First update your apt index again.

sudo apt-get update

Now your system are ready for install docker:

sudo apt-get install docker-ce docker-ce-cli

Set up Portainer

For deploy and update we will use docker compose. Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration.

Here is an example compose file:

version: "3.7"
    image: portainer/portainer:latest
    command: --host=unix:///var/run/docker.sock
    - /var/run/docker.sock:/var/run/docker.sock
    - portainer-data:/data
    - aviation
      mode: global
    driver: local
    name: hugo
    attachable: true

Save it as host.yml. To start portainer simple run follow command:

docker-compose -c host.yml up

Next open portainer on https://«your host»:9000

It will ask to create user and set password for it:

Portainer init

Next you will show follow picture:

Portainer init
