Docker 101

[@NathanSMS26]

This series is higher quality than I received from certain classes for a masters in robotics, its amazing that this is available for free

[@ArticulatedRobotics]

Thanks for your kind words, I'm glad you found it helpful!

[@marijnderijk1843]

True

[@Snooperking]

please keep making content, seriously you are so good at explaining things. Keep it up and your channel will blow up, idk how you only have 15k subs right now, don't give up man you're a godsend.

[@ArticulatedRobotics]

Thank you!

[@mshytb]

Working as a software engineer for ros2 applications for the first time, and your videos are helping me through it. Thanks for the amazing (FREE) content. If you ever produce a paid course, I will be one of the first to buy.

[@Hanschanhs]

Really looking forward to future instalments of this series - literally thinking hours earlier that I could do with the next Docker for ROS tutorial from your channel. Keep up the fantastic informative content!

[@ArticulatedRobotics]

Thanks, and what great timing!

[@mikekopack6441]

This is/will be a great series and is really useful. I HIGHLY recommend people work this way as it helps separate the whole "HostOS version vs ROS OS version" linkage which can be a serious headache. This way you can technincally run the latest version of ROS on an older host OS, or an older ROS version on a newer OS version, and it also helps keep your host environment clean and uncluttered - no extra packages or package version conflicts between projects, etc. - they're all inside the docker containers instead with the code that needs them.

[@ArticulatedRobotics]

Yep - it takes a very annoying problem and totally removes it!

Ok, I'm just going to watch all your videos. You are just too good at structuring the materials. I also have the habit of learning while documenting, so i have cheat sheets when i forget about commands across so many software in use. But your arrangements are so much clearer and attentive to details, as well as drawing out different layers of abstractions. It saves massive time for beginners!

[@pranavshevkar269]

Thankyou for the video. This series has helped me tremendously during my masters thesis. I am at the point where i have to document my software development and dockerising it would be the best way to make sure that anyone else who would like to use my work would easily be able to reproduce it. I am eagerly waiting for your next video.

[@ArticulatedRobotics]

Thanks!

[@AsantePE]

First time I will not skipp the commercial you deserve it!

[@Cian-_-]

so useful man, thank you so much! I always find it so hard to learn new software as the entrypoint is so badly documented, but you're videos are making it so easy and engaging!

[@ambertheobald6995]

Clearest and most helpful ROS video I've seen!

[@ambertheobald6995]

* ROS + Docker

[@SantiDiazC]

I watched other videos about docker but yours are the best and outstanding! Thank you!

[@jayeshagarwal5638]

Thanks man! you don't know how much you've helped:)

[@marijnderijk1843]

Thanks!! Cant wait for the next vids, ill be recommending these videos and your channel to my fellow robotics masters students next quarter!

[@piyushmahamuni4613]

This is going to help me so much to organize and simplify my workflow. I can't remember how many times I've reset my systems because of broken dependencies.

[@xverosity]

Most helpful tutorial for Docker, was easy to understand and follow

[@arbe]

Looking forward to the next video.

[@saidinesh9980]

Just installed docker in rpi and found this video. Love you brother ❤️. From India

[@ArticulatedRobotics]

Thanks!

[@logandihel]

This is super helpful. Ive been trying to learn docker on and off for years but the learning curve seemed too steep. Thank you!

[@messedmushroom]

So helpful! Excited for the next video

[@mariadelmar2497]

Thank you so much for the video, it is great! Will you make another video on deploying Gazebo and RVIZ inside a Docker container? It's been impossible for me to achieve it... Looking forward for your next video!

[@hunrahel]

I find that Docker targets and contexts are very important as complexity increases And docker-compose is going to play really nice with ros launch, so looking forward to that

[@ArticulatedRobotics]

Thanks, yes there are some great tools to explore!

[@hunrahel]

@@ArticulatedRobotics actually, if you're open to requests, I'd love to someday see a tutorial on microros for raspi pico within docker. The toolchain's for the specific combo has been resisting me.

[@Must23]

Honestly this is the best docker tutorial I have found in the entire youtube. Big shout-out to you! I wanted to know if there's a way to update for example if I have to add another package inside my image file, since I will be mainl use docker to study ROS2, thats why I need my image to be versatile. You kinda touched the subject towards the end by stating about binds mount, ut what I have in mind is thats once you contain and image, its like an offline package, not like virtual machine where you can sudo apt or gitclone inside the container. Please advice! And again thank you so much~!

[@obensustam3574]

Looking forward to see upcoming videos on this topic 🤓

[@MuhammadrizoMarufjonov-os5fv]

Thanks a lot. You are saving my life)

[@robinli5499]

This video is really helpful for beginners to use docker. Thanks so much. One little request is could you please make videos to show how to organise ros2 projects on one machine? I have multiple ros2 pkgs and their docker images. Is it better to create a new image based all of them, or is it better to run them in parallel and enable communication among them?

[@birendrakumar-gl5gq]

you can use terminator (terminal emulator), it makes the work easy, when we have work on multiple terminal

[@henkjekel4081]

Hi @ArticulatedRobotics :) I'm building a complex software system for my Master Thesis in Robotics. It doesnt involve ROS, but I still feel that using docker would be beneficial. Could you tell me when you would recommend not to use docker, because after watching your series I feel like it is always better to use Docker than not to use Docker. Thank you for the amazing videos:) Kind regards, Henk

[@andreasg.dpetersen4252]

Amazing stuff man, really appreciate your content. It's incredibly helpful and practical and making it much easier to start learning and using Docker and ROS in robotics. Keep up the good work 🦾

[@ArticulatedRobotics]

Thank you!!

[@AbdulAhad-eg3se]

Thank you for this !

[@octavioaguila9276]

Your videos are amazing :) Thank youuu

[@ArticulatedRobotics]

Thank you!

[@mikekopack6441]

So we use a 2 stage process where I work... First, have a "base" dockerfile which starts from the standard ROS docker image (of choice), and that first script adds in any proxy setup, port mappings, apt packages, pip packages, and any 3rd party code that has to be compiled from source, that we need for our project to that image to create a new "base image". Then we use a 2nd dockerfile which uses the first image as base and maps our code directory on the host system over to the image, and performs our ROS2 colcon build to build our code into the new runnable image. Then we use docker-compose files to start up the container(s) and start the individual nodes we need started. This way we only rebuild the first "base" image when we need new packages added to the environment (which is much less often) and most of the time we rebuild just by running the 2nd dockerfile to rebuild/recompile/update the containers with new code as we go. This makes things really quick and easy.

[@ArticulatedRobotics]

Thanks Mike, I really appreciate this, I feel like there aren't many people sharing (for lack of opportunity) the details of how they put this stuff into practice. At our workplace I haven't used Docker too much as we usually just install on bare metal, but in the instances we have, I used exactly the configuration you described, and now that I think of it, I should probably detail that in a future video!

[@mikekopack6441]

@@ArticulatedRobotics YES PLEASE!!! I know when we started trying to do this on one of my projects back around Nov 2021 there were very few references online as to the right way to do ROS on Docker, and it took me about a month of struggling to come up with what we ended up with (which is now acting as a template for every project we do). I'm SURE others would benefit from your videos showing how to do it and how flexible it makes things. My setup was for a ROS1 project, but I'm working on switching it over to a ROS2 now...

[@arjenrobin96]

Thanks for sharing this. One question: How do you setup GPUs accordingly? I had issues with 2 machines, because one had a Nvidia GPU and the other didn't. The result then was, that rqt_graph would work, but RViz not (still launches, but screen stays black). Thanks:)

[@mikekopack6441]

@@arjenrobin96 ooh good question, I haven’t tried running Rviz nor gazebo from inside a container, but have run other guis. We have a Python based GUI we use on my program and we’re able to run that from within… but haven’t tried anything that requires Nvidia gpu. I know there is a way yo do it, but you likely need to have the nvidia gpu on the host - running inside of a container doesn’t get you around that requirement if there is such a dependency…

[@ronygab]

Like always great video

thanks ., How to run camera in docker using ros ?

[@ArticulatedRobotics]

Great question, I will be covering this in a later video (should basically be a matter of mapping the device through)

wow

[@ifedayoolusanya7466]

hi i'm currently trying to run apt and build the dockerfile on a pi5. However when I write the exact code you have, i get this error below ERROR: failed to solve: process "/bin/sh -c apt-get update && apt-get install -y nano rm -rf /var/lib/apt/lists/*" did not complete successfully: exit code: 100

[@ifedayoolusanya7466]

any idea how I can go about solving this
