• [x] Add dockerfile to build busola with all configuration inside. Proposal: create kymadirectory in busola - https://github.com/kyma-project/busola/pull/3321, https://github.com/kyma-project/busola/pull/3332
• [x] Add github actions to build new image type
• [x] Add integration tests from kyma-dashboard - https://github.com/kyma-project/busola/pull/3333

Cleanups and known issues

• [ ] When there is no yaml for specific resource, busola by default serves js and consume it. Which results in high cpu usage and many warnings, errors in console. https://github.com/kyma-project/busola/pull/3367
• [ ] Unify cypress commands in tests Attachments
