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

[piyushmahamuni]

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.

[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.

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.

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!

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.

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!

[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!

[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

[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!

[SantiDiazC]

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

[saidinesh]

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

[marijnderijk]

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

[xverosity]

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

[obensustam]

Looking forward to see upcoming videos on this topic 🤓

[mariadelmar]

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!

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~!

[messedmushroom]

So helpful! Excited for the next video

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.
