Installing Docker on Linux

To begin the installation of Portainer, we first need to ensure that Docker is properly set up on your Linux system. Docker is a powerful platform that allows you to run and manage containers, making it an essential component for using Portainer.

Here are the steps to install Docker on your Linux system:

1. 1. Update the package index and upgrade existing packages by running the following commands in your terminal:

1. 1. Add the official Docker repository by running the following command:

1. 1. Import the Docker GPG key by running the following command:

1. 1. Add the Docker repository to your system by running the following command:

1. 1. Update the package index again by running the following command:

1. 1. Install the latest version of Docker by running the following command:

Once Docker is installed, you can proceed with the installation of Portainer and start managing your Docker containers with ease.

Creating a Docker Volume and Pulling the Portainer Image

Once Docker is installed, the next crucial step is creating a Docker volume and pulling the Portainer image. A Docker volume is a persistent storage area that allows containers to share and persist data. To create a volume, use the

command followed by a name for the volume. For example:

1	docker volume create portainer_data

After creating the volume, you can pull the Portainer image from the official Docker Hub repository. Pulling an image means downloading it from the repository to your local environment. Use the

command followed by the image name and tag. For example, to pull the latest version of the Portainer image, use:

1	docker pull portainer/portainer

Once the image is pulled, you can verify its presence by running the

command, which will display a list of all the images in your local Docker environment. Look for the Portainer image in the list to ensure it was successfully pulled.

Table: Docker Volume and Portainer Image Setup

With the Docker volume and Portainer image set up, you are now ready to proceed with the next steps in the installation process. These steps will help you start a Portainer Server container and configure it to manage your Docker environment effectively.

Starting a Portainer Server Container

With the Docker volume and Portainer image in place, it’s time to start a Portainer Server container and gain access to the powerful Portainer dashboard. To do this, we will use the

command. Open your terminal or command prompt and enter the following command:

This command starts a new container named “portainer” using the Portainer image. It maps the Portainer dashboard to port 9000 on the host machine, and mounts the Docker socket and a volume for data persistence. The

flag runs the container in detached mode, allowing it to run in the background.

Once the container is running, you can access the Portainer dashboard by opening a web browser and entering

in the address bar. This will take you to the Portainer login page.

Logging in to the Portainer Dashboard

To log in to the Portainer dashboard, follow these steps:

1. Enter a username of your choice in the “Username” field.
2. Enter a strong password in the “Password” field.
3. Confirm your password in the “Confirm Password” field.
4. Click on the “Create User” button to create your admin account.

Once you have created your admin account, you will be redirected to the Portainer dashboard. From here, you can start managing your Docker containers, images, networks, volumes, and more.

Congratulations, you have successfully started a Portainer Server container and gained access to the Portainer dashboard. Take some time to explore the dashboard and familiarize yourself with its features. It’s a powerful tool that will simplify your Docker management tasks and enhance your container operations.

Creating an Admin Password and Adding Environments

To ensure the security of your Docker management, let’s create an admin password for Portainer and explore how to add other environments using Portainer Agent containers.

1. Start by accessing the Portainer web UI on your Docker environment. Once logged in, navigate to the “Settings” tab.

2. Under the “Security” section, locate the “Admin Password” field. Enter a strong and secure password to protect your Portainer instance.

3. Save the changes, and the admin password will be set for Portainer.

Now, let’s proceed with adding other environments using Portainer Agent containers:

1. Start a new Portainer Agent container by running the following command:

1	docker run -d -p 9001:9001 --name portainer_agent --restart always -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker/volumes:/var/lib/docker/volumes portainer/agent

This command will start the Portainer Agent container and enable it to communicate with your Docker environment.

2. After the Portainer Agent container starts, go back to the Portainer web UI and navigate to the “Endpoints” tab.

3. Click on the “Add Endpoint” button and fill in the required information, including the URL of the new environment and a name for easy identification.

4. Save the changes, and Portainer will now have access to the additional environment.

By creating an admin password and adding other environments, you can enhance the security and flexibility of your Docker management with Portainer.

Testing the Portainer Setup

Before we move forward, let’s verify the successful installation of Portainer by deploying a test Docker container using the setup we’ve created. This will ensure that Portainer is correctly configured and ready for managing your Docker environment.

To begin, open a terminal or command prompt and execute the following command to deploy an NGINX web server container:

1
$ docker run -d -p 80:80 --name my-nginx nginx

This command will create a container named “my-nginx” running the latest version of the NGINX web server image. The “-p 80:80” flag maps port 80 of the container to port 80 of your local machine, allowing you to access the NGINX web server through your web browser.

Once the container is running, open your web browser and enter “http://localhost” in the address bar. If everything is set up correctly, you should see the default NGINX welcome page, indicating that the test container is running successfully.

Test Container Information

This table displays the information about the test container. The “Container Name” column shows the name you specified when running the container. The “Image” column displays the image used to create the container. The “Status” column indicates whether the container is running or stopped. Finally, the “Ports” column shows the port mapping for accessing the container’s services.

Congratulations! You have successfully tested your Portainer setup by deploying a test Docker container. This confirms that Portainer is installed and configured correctly, allowing you to effectively manage your Docker environment.

Installing Portainer on Ubuntu

If you’re using Ubuntu as your operating system, follow these steps to install Portainer and start managing your Docker containers effortlessly.

First, make sure you have the latest version of Docker installed on your system. To do this, you can add the official Docker repository, update your package lists, and install Docker using the following commands:

$ sudo apt-get update

$ sudo apt-get install

Configuring Portainer on Ubuntu

With Portainer successfully installed on your Ubuntu system, let’s now configure it to ensure seamless Docker management. Follow these steps to set up Portainer and start managing your Docker containers with ease.

Accessing the Portainer Web UI

After installing Portainer, you can access the Portainer web UI by opening your preferred web browser and entering the IP address or domain name of your Ubuntu system followed by the Portainer port (default is 9000). For example, if your Ubuntu system’s IP address is 192.168.0.100, you would enter “http://192.168.0.100:9000” in your web browser’s address bar. This will take you to the Portainer login page.

Creating an Admin Password

Upon accessing the Portainer web UI, you will be prompted to create an admin password. Choose a strong password to ensure the security of your Portainer environment. This password will be required whenever you log in to Portainer in the future.

Connecting to Your Local Docker Environment

Once you have set up the admin password, you will be prompted to connect Portainer to your local Docker environment. Click on the “Local” option to connect to the Docker daemon running on your Ubuntu system. Portainer will automatically detect and connect to the Docker environment.
