DOCKER_RUNTIME variable is not set in docker-compose

[ACTP0H0M]

Hello, I get the following error when trying to install ur3 repository with Docker:

Command:

$ docker-compose build

Error:

WARNING: The DOCKER_RUNTIME variable is not set. Defaulting to a blank string. ERROR: The Compose file './docker-compose.yml' is invalid because: Unsupported config option for services.ros_ur3: 'runtime'

Any idea what this argument should be or where is it read from?

Hi @ACTP0H0M,

About that, you need to set that parameter in your local machine. Either temporarily as export DOCKER_RUNTIME=nvidia if you have NVIDIA drivers or DOCKER_RUNTIME=runc if not. You can set that line in your ~/.bashrc profile file to have it automatically set every time you open a new terminal

Hello, first I want to thank for your excellent work in this repository.

I would like to reopen this issue since I have the same problem trying to use "docker-compose build", even I set up export DOCKER_RUNTIME=nvidia or export DOCKER_RUNTIME=runc in ~/.bashrc, it gives the following issue:

I wonder if there are other options as "runc" that can solve it. Unfortunately, I don't know much about drivers.

I am using the melodic branch and Ubuntu 18.04 in a ThinkPad t420.

Thank you so much!

Hi @NigerChel

Do you have the latest version of docker-compose? The problem seems unrelated to this package. Rather is a problem with docker-compose. See here https://github.com/docker/compose/issues/6436

Hi @cambel

Thanks for your response, after upgrading docker-compose it fixed the problem by using the following lines:

$ sudo apt-get remove docker-compose $ sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose $ sudo chmod +x /usr/local/bin/docker-compose $ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Now I faced with this problem of dependencies, it seems it fails the "docker-compose build" in the Dockerfile in these lines:

Updating ROSDEP and installing dependencies

RUN cd ~/ros_ws \ && rosinstall ~/ros_ws/src /opt/ros/$ROS_DISTRO src/ros_ur3/dependencies.rosinstall \ && apt-get update \ && rosdep fix-permissions \ && rosdep update \ && rosdep install --from-paths src --ignore-src --rosdistro=$ROS_DISTRO -y \ && rm -rf /var/lib/apt/lists/*

Any idea will be very helpful !!

Thanks in advance.

Melodic is no longer maintained, so I would suggest using Noetic.

If you still want to try Melodic, see this post to fix your current problem. https://answers.ros.org/question/400079/error-the-following-packagesstacks-could-not-have-their-rosdep-keys-resolved-to-system-dependencies/
