This is a simple UI meant to test and demonstrate a blue-green or a canary deployment. It will query the /version URI of the same host to check if there are any changes.
There are multiple available tags on the dockerhub repository. Use the latest tag (or greatest) to access the WEBUI, then start your deployment using any other version. all versions should work as webui, however the latest will be the cleanest.
For each version there will be two semi-identical images, ying and yang.
docker run -p 8080:8080 kalioz/canary-deployment-ui:ying
# ctrl-c
docker run -p 8080:8080 kalioz/canary-deployment-ui:yangThe image is published on the repository kalioz/canary-deployment-ui
See kalioz/canary-deployment-ui for more information.
