ovsdbviz

Interactive demo — all schemas from the latest OVS/OVN trees, rendered in your browser (requires GitHub Pages enabled: Settings → Pages → Deploy from branch → master → /docs).

How to run

$ GOBIN=`pwd` go install github.com/halfcrazy/ovsdbviz@latest
$ ./ovsdbviz --schema ./examplesvswitch.ovsschema --out ./ovsdb1.dot
$ ./ovsdbviz --db OVN_Northbound --address 192.168.1.1:6641 --out ./ovsdb2.dot
$ yum install graphviz
$ dot -Tpng ./ovsdb.dot -o ./ovsdb.png
$ open ./ovsdb.png

Interactive HTML output

--format html produces a single self-contained HTML file (Cytoscape.js + ELK layered layout via CDN, no build step):

• Multiple schemas in one page: repeat --schema or pass files as positional args; switch schemas from the dropdown
• Click a table: keeps only its direct & transitive relations and re-layouts the subgraph (fewer crossings); click blank space to restore
• Edges leave from the exact field row, like Graphviz record ports; red = key reference, blue = value reference, dotted = weak reference (RFC 7047)
• "Show all columns" renders every column as a record row; by default only referencing columns are shown
• "Load JSON…" adds schemas generated with --format json at runtime

$ ./ovsdbviz --format html --out ./ovsdb.html examples/*.ovsschema
$ open ./ovsdb.html
