1. generate index image
zhaoxia@xzha-mac test % mkdir catalog
zhaoxia@xzha-mac test % ../bin/opm generate dockerfile catalog
zhaoxia@xzha-mac test % cat catalog.Dockerfile 
# The base image is expected to contain
# /bin/opm (with a serve subcommand) and /bin/grpc_health_probe
FROM quay.io/operator-framework/opm:latest


# Configure the entrypoint and command
ENTRYPOINT ["/bin/opm"]
CMD ["serve", "/configs", "--cache-dir=/tmp/cache"]


# Copy declarative config root into image at /configs and pre-populate serve cache
ADD catalog /configs
RUN ["/bin/opm", "serve", "/configs", "--cache-dir=/tmp/cache", "--cache-only"]


# Set DC-specific label for the location of the DC root directory
# in the image
LABEL operators.operatorframework.io.index.configs.v1=/configs

zhaoxia@xzha-mac test % docker build . -f catalog.Dockerfile -t quay.io/olmqe/nginxolm-operator-index:2726 
zhaoxia@xzha-mac test % docker push quay.io/olmqe/nginxolm-operator-index:2726
