docker run -d --name=cratedb --restart=always --network=host \
    -v /opt/cratedb/data:/data \
    crate -Cdiscovery.type=single-node

• User-defined bridge network

User-defined bridge network can be used for listening on different port. By default, CrateDB transport service is listening on port 4300 and CrateDB Postgres service is listening on port 5432. Admin UI is available on port 4200. Ports can be changed with -p option.

docker network create app-net

docker run -d --name=cratedb --restart=always --network=app-net \
    -p 8080:4200 -p 8081:4300 -p 8082:5432 \
    -v /opt/cratedb/data:/data \
    crate -Cdiscovery.type=single-node

Testing CrateDB

To access admin UI, open a web browser and go to http://<IP_ADDRESS>:4200, where <IP_ADDRESS> is the IP address of the system.

Uninstall CrateDB

To completely remove CrateDB, remove its container:

docker rm --force cratedb

Remove CrateDB image:

docker rmi crate

You can also remove CrateDB data:

sudo rm -rf /opt/cratedb

If a user-defined bridge network was created, you can delete it as follows:

docker network rm app-net
