The help message of "opm alpha render-graph" is not correct, it generates mermaid-formatted view of upgrade graphs of operators in an index, not a bundle, so the input should be index-image or fbc-dir, not a bundle-image.

Generate mermaid-formatted view of upgrade graphs of operators in an index


Usage:
  opm alpha render-graph [index-image | fbc-dir | bundle-image] [flags]


Examples:


#
# Output channel graph of a catalog in mermaid format
#
$ opm alpha render-graph quay.io/operatorhubio/catalog:latest


#
# Output channel graph of a catalog and generate a scaled vector graphic (SVG) representation
# Note:  this pipeline filters out the comments about lacking skipRange support
#
$ opm alpha render-graph quay.io/operatorhubio/catalog:latest | \
    grep -Ev '^<!--.*$' | \
    docker run --rm -i -v "$PWD":/data ghcr.io/mermaid-js/mermaid-cli/mermaid-cli -o /data/operatorhubio-catalog.svg


# Note:  mermaid has a default maxTextSize of 30 000 characters.  To override this, generate a JSON-formatted initialization file for
# mermaid like this (using 300 000 for the limit):
$ cat << EOF > ./mermaid.json
{ "maxTextSize": 300000 }
EOF
# and then pass the file for initialization configuration, via the '-c' option, like:
$ opm alpha render-graph quay.io/operatorhubio/catalog:latest | \
    grep -Ev '^<!--.*$' | \
    docker run --rm -i -v "$PWD":/data ghcr.io/mermaid-js/mermaid-cli/mermaid-cli -c /data/mermaid.json -o /data/operatorhubio-catalog.svg
