I tried searching, and the only think I found was that someone said it is not possible to change exposed ports.Īlso, I would need to clone the container for Hortonworks for 15 users (not simultaneous) all using different, preferably internal private IP addresses, and/or different exposed ports.

I cannot figure out how to change either one to use a different exposed port so there is not a port conflict.
Docker desktop keep ports from changing on reboot install#
i tried to install portainer to manage the Docker containers, and it shares an exposed port. What I have tried so far is to install Docker on CentOS and install the Hortonworks installer script, which installs about 30-40GB worth of data. When you open the browser and navigate to the Docker host on port 8080, you will see Jenkins up and running.I have been tasked with using Docker or VM's to deploy Hortonworks for students in a class on a shared server.

The left-hand side of the port number mapping is the Docker host port to map to and the right-hand side is the Docker container port number. So, you need to run the following command − The containers were sorta working, but theyd get the occasional files corrupting like the Redis rdb on my Mailcow instance. Try to restart the compose files, it would complain that the ports were in use.

To run Jenkins and map the ports, you need to change the Docker run command and add the ‘p’ option which specifies the port mapping. Look at systemctl status docker, full of active container processes. One is the data port of 8080 and the other is the control port of 50000. If we observe the output, we can see that there is a section of "ExposedPorts" and see that there are two ports mentioned. The output of the inspect command gives a JSON output. The low-level information of the image or container in JSON format. SyntaxĬontainer/Image − The container or image to inspect This method allows one to return low-level information on the container or image. Let’s now learn more about this inspect command.

Step 5 − Now go to the Ubuntu server and run the command −

This will be used to download the Jenkins Image onto the local Ubuntu server. Step 4 − If you scroll down on the same page, you can see the Docker pull command. The way quin452 puts it - with minor revision: Get the container ID: docker ps -a. You can change the ports of a docker container without deleting it. Step 3 − Next, let’s browse and find the Jenkins image. The left-hand port number is the docker host port - your computer - and the right-hand side is the docker container port. Step 2 − Once you have signed up, you will be logged into Docker Hub. Step 1 − First, you need to do a simple sign-up on Docker Hub. We are then going to map the Jenkins port number to the port number on the Docker host. In our example, we are going to download the Jenkins container from Docker Hub. Let’s look at an example of how this can be achieved. NOTE: Be sure to account for disk space requirements for the docker volume created above. sudo docker volume create splunk-sc4s-var. Edit the container’s file hostconfig.json (usually in /var/lib/docker/containers/ ID/hostconfig.json) and add or replace ports. This will also be used to keep track of the state of syslog-ng between restarts, and in particular the state of the disk buffer. When you run a container, if you want to access the application in the container via a port number, you need to map the port number of the container to the port number of the Docker host. When the Docker service stops, edit the hostconfig.json file Here is the whole procedure: Stop the container. In Docker, the containers themselves can have applications running on ports.
