Typically, running an out-of-date bundler
will not cause any issues, so you should be able to safely ignore the Warning.
However, if you must update the version of bundler
for some reason, you should use an .s2i/bin/assemble
script to update the version of bundler
prior to the default build process. So something similar to
#!/bin/bash -e
# The assemble script builds the application artifacts from source and
# places them into appropriate directories inside the image.
echo "---> Updating bundler gem..."
gem install bundler
# Execute the default S2I script
source ${STI_SCRIPTS_PATH}/assemble
should do the trick. If you add this to your repository in the .s2i/bin
directory as an executable assemble
script (definition don't forget to chmod +x assemble
before adding this to your repository), this should take care of the issue for you.
You can also see the default Ruby 2.5 assemble
script in the sclorg
GitHub repo: https://github.com/sclorg/s2i-ruby-container/blob/master/2.5/s2i/bin/assemble. Just change the version in the URL as needed in case your curious.
