Detailed Instructions:
Step 1
This command will get the latest version of eclipse-mosquitto and run it.
-d option runs it in the background, so you don't need to keep your ssh session open. And
--name will name the container eclipse-mosquitto1. This is useful because all future commands will use the container name to interact this this container. Otherwise, you'd need to use randomly generated container id.
Note: We're simply running the barebone version of eclipse-mosquitto container with below command, after which, we will use the commands bellow to learn more about the eclipse-mosquitto docker container and then we'll be able to come-up with the final command to run based on our needs, to spin-up a properly configured eclipse-mosquitto container.

docker run -d --name eclipse-mosquitto1 eclipse-mosquitto:latest
Step 2
Now that we ran the command to run the container, we need to check its status.
This command will only display the status for eclipse-mosquitto1 container.
Run docker ps without the filter, to display all running containers on the system.
This command will only display the status for eclipse-mosquitto1 container.
Run docker ps without the filter, to display all running containers on the system.
docker ps --filter name=eclipse-mosquitto1
Step 3
There is another way to check the status/state of the container and that's with docker inspect.
Sometimes, if the container exits or crashes, they may not be listed with docker ps, unless you do docker ps --all
But use the this docker inspect command to get more details on eclipse-mosquitto1 container status.
But use the this docker inspect command to get more details on eclipse-mosquitto1 container status.
docker inspect eclipse-mosquitto1 | grep -A12 "State"
Step 4
One of the most frequently docker command used is docker logs.
docker logs command is used to retrieve the logs output from the container. If there are any errors or issues or to check on the console output from the container, use the docker logs command.
Use the docker logs command below to display the logs for eclipse-mosquitto1 container.

Use the docker logs command below to display the logs for eclipse-mosquitto1 container.
docker logs eclipse-mosquitto1
Step 5
In most cases, docker containers must expose a port so that it can be mapped with host machine's ports. This allows for interact with container app from outside the container.
eclipse-mosquitto documentation should show which ports are exposed, however, the most reliable way is for you to check the exposed ports directly from the running container. Use the command below to displays the exposed ports, which you can then use to map with host computer's ports.

docker inspect -f "{{ .Config.ExposedPorts }}" eclipse-mosquitto1
Step 6
Docker Volumes are also essential for running docker containers in production. Essentially, they allow you to map host computer's folder directly inside container. This helps with maintaining state or data of the container.
For instance, if eclipse-mosquitto1 container crashes for any reason, the data produced by this app will be lost. The solution is to use Volumes so that even if the container crashes, the data will reside outside of the container, hence, it will be preserved.
To properly use Volumes, they must be configured by the creators of the docker image, in this case, by eclipse-mosquitto image creators. The best way to find the available volumes already configured in eclipse-mosquitto1 container is by using the command below. Which will list the available volumes for you to use and potentially map with host computer's directories.

docker inspect -f "{{ .Config.Volumes }}" eclipse-mosquitto1
Step 7
Environment Variables are also an essential part of docker containers. In fact, it is a best practice to use Environment Variables for any dynamic configuration options. This includes, important settings, usernames, password, database connection settings and so on.
eclipse-mosquitto docker documentation should explain the available Environment Variables for eclipse-mosquitto image. However, it's sometimes best to just check and see what are all available and configured Env Variables for eclipse-mosquitto1 container.
Use the commands below to display all configured Environment Variables for eclipse-mosquitto1 container and their default values if any. I usually like using the first command, as the result is well formatted, but it's not as precise and may include extra json. Use both options when not sure.

docker inspect eclipse-mosquitto1 | grep -A50 "Env"
docker inspect -f "{{ .Config.Env }}" eclipse-mosquitto1
Step 8
Docker Stop command is used to shutdown a container, it's like shutting down the computer. However, it is not removed and data/configuration is maintained, you can start the container when needed.
Stopping a container also removes it from some of the default places shown, i.e. if you do docker ps, it will not show there by default anymore.
Stopping a container also removes it from some of the default places shown, i.e. if you do docker ps, it will not show there by default anymore.
docker stop eclipse-mosquitto1
Step 9
Docker Start will start the container, just like the name suggests. It's self-explanatory and you can use the command below.
docker start eclipse-mosquitto1
Step 10
Docker Pause command does not stop the container, instead it suspends all processes on eclipse-mosquitto1 container, and it's much quicker to UnPause it and get it running again.
docker pause eclipse-mosquitto1
Step 11
Docker UnPause will simply un-pause our eclipse-mosquitto1 container and make it run again.
docker unpause eclipse-mosquitto1
Step 12
One of the most important and useful features of docker containers is being able to get shell access to the container. Once you get the shell access, you can directly interact with the container.
This is one of the most often used features because often, you'll need to go into the shell of the container and run commands, install additional software, change configuration, look at logs, etc.
Just keep in mind, if you install or change anything inside the container outside of the Volume folders, you will lose those changes if the container crashes or when you re-deploy it. Essentially, by installing/altering the container, you have now modified it and have a custom container.
However, it's still a very useful command.

To get shell access to our eclipse-mosquitto1 container, run the command below.
docker exec -it eclipse-mosquitto1 /bin/sh
Step 13
In our prior Step, we discussed how eclipse-mosquitto container can be modified from the shell access. But what if you want to keep those changes that are not in the Volume folders.
There is a way to do that as well. Use the command below to essentially save the state of the eclipse-mosquitto1 container and give it a custom name, i.e. my-custom-eclipse-mosquitto1.
There is a way to do that as well. Use the command below to essentially save the state of the eclipse-mosquitto1 container and give it a custom name, i.e. my-custom-eclipse-mosquitto1.
docker commit eclipse-mosquitto1 my-custom-eclipse-mosquitto1:latest
Step 14
When you're doing with all your testing or want to remove/delete eclipse-mosquitto1 container, use the command below.
Docker rm will remove and delete the container and its contents/data.
If you have configured Volumes, this will NOT delete the volume data on host computer. This will only remove eclipse-mosquitto1 container.
Docker rm will remove and delete the container and its contents/data.
If you have configured Volumes, this will NOT delete the volume data on host computer. This will only remove eclipse-mosquitto1 container.
docker rm -f eclipse-mosquitto1
Step 15
Even if you remove/delete eclipse-mosquitto1 container with docker rm command, it will not delete the actual eclipse-mosquitto base image that was downloaded to be used for eclipse-mosquitto1. It caches it locally, so if you spin-up a second eclipse-mosquitto container, it wouldn't need to download the base image again.
But sometimes you need to also remove these to save space on the host computer. Use the command below to remove eclipse-mosquitto image.
But sometimes you need to also remove these to save space on the host computer. Use the command below to remove eclipse-mosquitto image.
docker rmi -f eclipse-mosquitto
