How to install and configure Docker and Portainer on Ubuntu for preparing installing oracle database and oracle apex

In this tutorial, I will show you how to install Docker and Portainer on a Linux machine such as CentOS or Ubuntu.

The process is quite simple. You can copy and paste the code snippets below, and it should work directly.

My goal is to run various applications at the end. Using a graphical interface, I will create and save my scripts in a YAML file.

Additionally, Portainer offers many advantages for easily overseeing and managing my containers.

Various applications can be loaded into the containers, such as Nextcloud, NGINX Manager, PHP, Apache, MySQL, Oracle Database, and Oracle APEX.

Later on, I will show you how to install and configure the Oracle Database and Oracle APEX in a container.

Step 1: Setting up Docker

1. Add the Repository Key

First, we need to add the GPG key for the Docker repository to ensure the authenticity of the downloaded packages.

 

Bash

xxxxxxxxxx

 

1

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

2. Add the Docker Repository

Next, we add the Docker repository to the package sources so that we can install Docker from the official repository.

 

Bash

xxxxxxxxxx

 

1

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

3. Install Docker

Now, we update the package lists and install Docker.

 

Bash

xxxxxxxxxx

 

1

# Update the package lists

2

sudo apt update

3

​

4

# Install Docker

5

sudo apt install docker-ce docker-ce-cli containerd.io -y

4. Start and Enable Docker Services

Finally, we start the Docker service and enable it to start automatically at system boot.

 

Bash

xxxxxxxxxx

 

1

# Start the Docker service

2

sudo systemctl start docker

3

​

4

# Enable the Docker service to start automatically at system boot

5

sudo systemctl enable docker

Step 2: Setting up Portainer

1. Create a Docker Volume for Portainer

A Docker volume allows us to persist data even if the container is restarted or deleted. We create a volume for Portainer.

 

Bash

xxxxxxxxxx

 

1

sudo docker volume create portainer_data

2. Start the Portainer Container

Now, we start the Portainer container. Portainer is a lightweight management UI that allows us to easily manage our Docker environment.

 

Bash

xxxxxxxxxx

 

1

sudo docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce

Explanation of the above command:

• -d: Runs the container in detached mode (in the background).
• -p 8000:8000 -p 9000:9000: Maps ports 8000 and 9000 of the container to the same ports on the host.
• --name=portainer: Names the container "portainer".
• --restart=always: Ensures that the container always restarts if it crashes or the host is rebooted.
• -v /var/run/docker.sock:/var/run/docker.sock: Binds the host's Docker socket into the container, allowing Portainer to manage Docker.
• -v portainer_data:/data: Binds the previously created volume into the container to persist data.

3. Access the Portainer Web Interface

After setup, you can access Portainer via the following IP in your browser:

http://192.168.178.122:9000

4. Configure Portainer

It is best to go to the settings, then to configuration, and then to Public IP. There, you can enter the respective IP or domain name as needed.

Finally, under Settings → Environments → Configuration → Public IP, enter the IP: 192.168.178.122

Then you can click directly on the container port and access the graphical interface without constantly entering the IP in the browser URL.

Next Steps

• Set up Docker and Portainer: Follow the steps above to install Docker and Portainer on your Ubuntu system.
• Configure Portainer: Access the Portainer web interface and configure it according to your needs.
• Install additional applications: In future articles, I will show you how to install additional applications via Portainer.

As you have now seen, it is quite easy to install Portainer on a Linux machine.

In further articles, I will show you how to install additional applications via Portainer or the graphical interface.
