Why is WLP installUtility not able obtain assets from feature repo? - docker

Question

I am running docker build with following Dockerfile, with main idea to use feature repo as described https://github.com/WASdev/ci.docker#installing-liberty-features-from-local-repository-19008:
FROM websphere-liberty-kernel-ubi-min:19.0.0.9
COPY usr/ /opt/ibm/wlp/usr/
USER root
ARG FEATURE_REPO_URL=http://xyz.openshift.local/19.0.0.9/repo.zip
ARG VERBOSE=true
RUN configure.sh
RUN chown -R 1001:0 /tmp \
&& chmod -R g+rw /tmp \
&& chown -R 1001:0 /opt/ibm/wlp/output \
&& chmod -R g+rw /opt/ibm/wlp/output \
&& chown -R 1001:0 /opt/ibm/wlp/usr/servers/defaultServer \
&& chmod -R g+rw /opt/ibm/wlp/usr/servers/defaultServer \
&& chown -R 1001:0 /opt/ibm/wlp/usr/shared/resources \
&& chmod -R g+rw /opt/ibm/wlp/usr/shared/resources
USER 1001
Docker build output shows that repo.zip is downloaded and missing features are detected:

but then installation of all features fails:

Ensure that the specified assets are valid. To find the IDs of applicable assets, run the installUtility find command.
I have taken a look in downloaded repo.zip and I can find following file (that should match one of the missing features):
So, what is the reason for the error?

Answer 1

Using different image (ibmcom/websphere-liberty:some21.0.0.3version) and pointing FEATURE_REPO_URL to place where 21.0.0.3 repo is hosted works.
So whoever prepared 19.0.0.3 image for me and said which feature repo to use, pointed me to some incompatible artefacts.
What is interesting, when I combined different versions of image vs repo, configure.sh was nicely verbose (it explained there is incompatibility), but this error CWWKF1259E: Unable to obtain the following assets is really unhelpful.
