ros2 osrf docker container fails to build

asked 2020-04-16 07:09:58 -0600

Hello. I'm trying to build a dockerfile that extends the ones osrf is providing at https://hub.docker.com/r/osrf/ros2 and builds our company robot software. This is a first step towards setting up a CI system with jenkins and to simplify building for people that may not have the ros2 toolchain built and installed (maybe we can move to using a container vs. installing locally like we do now).

I've been having some issues with the build and put together two example projects that I can share that build with my local ros2 foxy install but won't build in the container.

The osrf/ros2:nightly is from yesterday.

The dockerfile is inline (because I can't attach it as I have less than 5 points...):

FROM osrf/ros2:nightly

# we want to be able to source
SHELL ["/bin/bash", "-c"]

# Install git
RUN apt-get update && \
    apt-get install -y git

# clone the test repos
RUN cd /root && mkdir -p ros2_workspace/src && \
    cd ros2_workspace/src && \
    git clone https://github.com/cmorganBE/ros2_server_example.git && \
    git clone https://github.com/cmorganBE/ros2_idl_example.git && \
    cd ros2_idl_example && git checkout 7091c75045f26d

# build the workspace
RUN cd /root/ros2_workspace && \
    source /opt/ros/foxy/setup.bash && \
    colcon build --symlink-install

CMD ["bash"]

I'm not planning or using the connext dds implementation but it looks like somehow this build expects it, although there aren't any errors about missing tools to generate the idl libraries either....

The output from the failed build is:

This is likely a bug in the automatic disabling of unavailable implementations from the warning above. I'd suggest that you check for a ticket and if one's not found open the ticket on rosidl: https://github.com/ros2/rosidl

This is a recent error that comes from the OSRF nightly archives.

Opened an issue at https://github.com/ros2/ros2/issues/903

In the meantime, if you want to use the latest version of the code and working around this issue, you can use the osrf/ros2:nightly-rmw-nonfree docker image and sourcing the RTI setup file before building.

FROM osrf/ros2:nightly-rmw-nonfree

# we want to be able to source
SHELL ["/bin/bash", "-c"]

# Install git
RUN apt-get update && \
    apt-get install -y git && \
    apt-get install -y libssl-dev

# clone the test repos
RUN cd /root && mkdir -p ros2_workspace/src && \
    cd ros2_workspace/src && \
    git clone https://github.com/cmorganBE/ros2_server_example.git && \
    git clone https://github.com/cmorganBE/ros2_idl_example.git && \
    cd ros2_idl_example && git checkout 7091c75045f26d

# build the workspace
RUN cd /root/ros2_workspace && \
    source /opt/rti.com/rti_connext_dds-5.3.1/setenv_ros2rti.bash && \
    source /opt/ros/foxy/setup.bash && \
    colcon build --symlink-install

CMD ["bash"]

Note that the need to install libssl-dev by hand is another issue that is being resolved independently

@cmorgan both the libssl-dev issue and https://github.com/ros2/rosidl_python... have been fixed

If you pull a recent version of the osrf/ros2:nightly image you should now be able to build your original dockerfile without modification

@marguedas I can confirm that it does work correctly now, thank you for opening a ticket and to Dirk for fixing it!
