In this article, we will guide you through the installation process of Dozzle on Ubuntu 22.04, ensuring that you can easily monitor your container logs and troubleshoot any issues that arise.

Prerequisites

Before we begin, please ensure that you have the following prerequisites in place:

1. A server running Ubuntu 22.04.
2. Root access to the server.

Step 1: Install Docker Engine

To begin the installation process, we need to install Docker Engine. Follow the steps below:

1. Install the necessary dependencies by running the following command:

apt install ca-certificates curl gnupg lsb-release -y

2. Add the Docker GPG key and repository by executing the following command:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor > /etc/apt/trusted.gpg.d/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list

3. Update the repository and install Docker Engine by running the following commands:

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

4. Verify the Docker version by executing the following command:

docker --version

Step 2: Launch Dozzle Container

Now that Docker Engine is installed, we can proceed with launching the Dozzle container. Follow the steps below:

1. Download and launch the Dozzle Docker container by running the following command:

docker run --name dozzle -d --volume=/var/run/docker.sock:/var/run/docker.sock -p 8888:8080 amir20/dozzle:latest

2. To verify that the Dozzle container has been successfully downloaded, execute the following command:

docker images

3. You should see the Dozzle container listed with the tag “latest” and relevant details.

Step 3: Access Dozzle Log Viewer

Now that the Dozzle container is up and running, you can access the Dozzle web interface through your web browser. Follow the steps below:

1. Open your web browser and enter the URL “http://your-server-ip:8888” (replace “your-server-ip” with the IP address of your server).
2. The Dozzle web interface will be displayed, providing you with an overview of your Docker containers.
3. Click on a specific container in the left pane to view its logs in real-time.
