Install Dozzle On Ubuntu

Dozzle is a docker based application. This means that, you need to already be having docker installed.

You can refer to these tutorials on how to install Docker and Docker compose on Ubuntu;

Install Docker CE on Ubuntu

Once you have Docker installed, then proceed to install Dozzle on Ubuntu using the command below;

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

The command will download the latest version of Dozzle docker image and create a container called dozzle using the same image.

You can enable container restart in case of any issue;

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

Dozzle docker container listens on port 8080 by default. To be able to access the Dozzle web interface, you can expose this port, 8080 to any free port on your host system.

For example, in the command above, we will access Dozzle docker container via the port 8888 on the host system.

Check the status of Dozzle;

docker ps --format '{{.ID}}\t{{.Image}}\t{{.Status}}\t{{.Ports}}\t{{.Names}}' | grep -i dozzle

9c48c6d58f6e	amir20/dozzle:latest	Up 4 minutes	0.0.0.0:8888->8080/tcp, :::8888->8080/tcp	dozzle

Dozzle is now up and running.

Confirm the ports are listening;
