Stop using canal! Alibaba Canal is really a shit. Bad docs, bad codes. Flink CDC is what you need.

This is the docker image for canal adapter.

You need to mount volume to canal-adapter config file to work properly.

See config file template: application.yml and Elastic DB adapter config file

docker run --name canal-adapter \ -v /path/to/application.yml:/usr/share/canal/adapter/conf/application.yml \ -v /path/to/es7:/usr/share/canal/adapter/conf/es7 \ -d youmianzz/canal-adapter:1.1.5 

• The work dir: /usr/share/canal/adapter.
• Log file: /usr/share/canal/adapter/logs/adapter/adapter.log, you may mount volume to the log file if you need.
