I am trying to build a docker container inside the pipeline. It fails with the following error:
failed to dial gRPC: unable to upgrade to h2c, received 403
My docker file contains the below lines:
# syntax=docker/dockerfile:1.2
FROM registry.access.redhat.com/ubi8/python-38
USER root
WORKDIR /app
CMD ["/bin/bash", "/app/runit.sh"]
Did you find a solution for this? Which image were you using for your pipeline?
We have seen this error with a node:16:13.0-alpine image for the pipeline. Rather than report that the docker command is undefined, the same error you had was given.
Removing "-alpine" from the pipeline image fixed the problem.
