ddocker container, completely remove Kafka in topic
1, into the container
docker exec -it 46fb57e04491 /bin/sh2, delete kafka storage directory (server.properties log.dirs configuration file, the default is "/ kafka / kafka-logs") related topic directory
3, Kafka delete the topic of command is
cd /opt/kafka_2.12-2.4.0/bin
./kafka-topics --delete --zookeeper 【zookeeper server】 --topic 【topic name】If kafaka boot loader configuration file when server.properties not configured delete.topic.enable = true, then the time of deletion are not really deleted, but the topic is marked as: marked for deletion
You can order: to view all topic
./kafka-topics --zookeeper 【zookeeper server】 --list At this point you really wants to remove it, you can do the following:
(1) Log zookeeper client: Command:
./bin/zookeeper-shell.sh --zookeeper 【zookeeper server】(2) Locate the directory where the topic:
ls /brokers/topics(3) to find the topic you want to delete, execute the command: you can, then topic deleted.
rmr /brokers/topics/【topic name】(4) Also marked for deletion are marked as the topic you can get by command zookeeper client:
ls /admin/delete_topics/【topic name】If you delete a topic here, then marked for deletion mark disappears
zookeeper's config also has information about the topic of: ls / config / topics / topic name [] I did not know what use
to sum up:
Completely remove topic:
1, delete kafka storage directory (server.properties log.dirs configuration file, the default is "/ tmp / kafka-logs") related topic directory
2, if you configure delete.topic.enable = true directly through the command to delete, if the command can not delete, delete directly through the zookeeper-client off topic to the next broker.
