You can view the [list of available versions](https://hub.docker.com/r/bitnami/cassandra/tags/) in the Docker Hub Registry. + +```console +docker pull bitnami/cassandra:[TAG] +``` + +If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values. + +```console +git clone https://github.com/bitnami/containers.git +cd bitnami/APP/VERSION/OPERATING-SYSTEM +docker build -t bitnami/APP:latest . +``` + +## Persisting your application + +If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed. + +For persistence you should mount a directory at the `/bitnami` path. If the mounted directory is empty, it will be initialized on the first run. + +```console +docker run \ + -v /path/to/cassandra-persistence:/bitnami \ + bitnami/cassandra:latest +``` + +or using Docker Compose: + +```yaml +cassandra: + image: bitnami/cassandra:latest + volumes: + - /path/to/cassandra-persistence:/bitnami +``` + +> NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID `1001`. + +## Connecting to other containers + +Using [Docker container networking](https://docs.docker.com/engine/userguide/networking/), an Apache Cassandra server running inside a container can easily be accessed by your application containers. + +Containers attached to the same network can communicate with each other using the container name as the hostname. + +### Using the Command Line + +In this example, we will create an Apache Cassandra client instance that will connect to the server instance that is running on the same docker network as the client. + +#### Step 1: Create a network + +```console +docker network create app-tier --driver bridge +``` + +#### Step 2: Launch the Apache Cassandra server instance + +Use the `--network app-tier` argument to the `docker run` command to attach the Apache Cassandra container to the `app-tier` network. + +```console +docker run -d --name cassandra-server \ + --network app-tier \ + bitnami/cassandra:latest +``` + +#### Step 3: Launch your Apache Cassandra client instance + +Finally we create a new container instance to launch the Apache Cassandra client and connect to the server created in the previous step: + +```console +docker run -it --rm \ + --network app-tier \ + bitnami/cassandra:latest cqlsh --username cassandra --password cassandra cassandra-server +``` + +### Using a Docker Compose file + +When not specified, Docker Compose automatically sets up a new network and attaches all deployed services to that network. However, we will explicitly define a new `bridge` network named `app-tier`. In this example we assume that you want to connect to the Apache Cassandra server from your own custom application image which is identified in the following snippet by the service name `myapp`. + +```yaml +version: '2' + +networks: + app-tier: + driver: bridge + +services: + cassandra: + image: 'bitnami/cassandra:latest' + networks: + - app-tier + myapp: + image: 'YOUR_APPLICATION_IMAGE' + networks: + - app-tier +``` + +> **IMPORTANT**: +> +> 1.

The `CASSANDRA_CLUSTER_HOSTS` parameter set the name of the nodes that set the cluster so we will need to launch other container for the second node. Finally the `CASSANDRA_NODE_NAME` parameter allows to indicate a known name for the node, otherwise cassandra will generate a random one. + +#### Step 3: Create a second node + +```console +docker run --name cassandra-node2 \ + --net=cassandra_network \ + -e CASSANDRA_CLUSTER_NAME=cassandra-cluster \ + -e CASSANDRA_SEEDS=cassandra-node1,cassandra-node2 \ + -e CASSANDRA_PASSWORD=mypassword \ + bitnami/cassandra:latest +``` + +In the above command a new cassandra node is being added to the cassandra cluster indicated by `CASSANDRA_CLUSTER_NAME`. + +You now have a two node Apache Cassandra cluster up and running which can be scaled by adding/removing nodes. + +With Docker Compose the cluster configuration can be setup using: + +```yaml +version: '2' +services: + cassandra-node1: + image: bitnami/cassandra:latest + environment: + - CASSANDRA_CLUSTER_NAME=cassandra-cluster + - CASSANDRA_SEEDS=cassandra-node1,cassandra-node2 + - CASSANDRA_PASSWORD_SEEDER=yes + - CASSANDRA_PASSWORD=password123 + + cassandra-node2: + image: bitnami/cassandra:latest + environment: + - CASSANDRA_CLUSTER_NAME=cassandra-cluster + - CASSANDRA_SEEDS=cassandra-node1,cassandra-node2 + - CASSANDRA_PASSWORD=password123 +``` + +### Initializing with custom scripts + +When the container is executed for the first time, it will execute the files with extensions `.sh`, `.cql` or `.cql.gz` located at `/docker-entrypoint-initdb.d` in sort'ed order by filename. This behavior can be skipped by setting the environment variable `CASSANDRA_IGNORE_INITDB_SCRIPTS` to a value other than `yes` or `true`. + +In order to have your custom files inside the docker image you can mount them as a volume. + +```console +docker run --name cassandra \ + -v /path/to/init-scripts:/docker-entrypoint-initdb.d \ + -v /path/to/cassandra-persistence:/bitnami + bitnami/cassandra:latest +``` + +Or with docker-compose + +```yaml +cassandra: + image: bitnami/cassandra:latest + volumes: + - /path/to/init-scripts:/docker-entrypoint-initdb.d + - /path/to/cassandra-persistence:/bitnami +``` + +### Configuration file + +The image looks for configurations in `/bitnami/cassandra/conf/`. As mentioned in [Persisting your application](#persisting-your-application) you can mount a volume at `/bitnami` and copy/edit the configurations in the `/path/to/cassandra-persistence/cassandra/conf/`. The default configurations will be populated to the `conf/` directory if it's empty. + +#### Step 1: Run the Apache Cassandra image + +Run the Apache Cassandra image, mounting a directory from your host. + +```console +docker run --name cassandra \ + -v /path/to/cassandra-persistence:/bitnami \ + bitnami/cassandra:latest +``` + +or using Docker Compose: + +```yaml +cassandra: + image: bitnami/cassandra:latest + volumes: + - /path/to/cassandra-persistence:/bitnami +``` + +#### Step 2: Edit the configuration + +Edit the configuration on your host using your favorite editor. + +```console +vi /path/to/cassandra-persistence/cassandra/conf/cassandra.yaml +``` + +#### Step 3: Restart Apache Cassandra + +After changing the configuration, restart your Apache Cassandra container for changes to take effect. + +```console +docker restart cassandra +``` + +or using Docker Compose: + +```console +docker-compose restart cassandra +``` + +Refer to the [configuration](http://docs.datastax.com/en/cassandra/3.x/cassandra/configuration/configTOC.html) manual for the complete list of configuration options. + +## TLS Encryption + +The Bitnami Apache Cassandra Docker image allows configuring TLS encryption between nodes and between server-client. This is done by mounting in `/bitnami/cassandra/secrets` two files: + +* `keystore`: File with the server keystore +* `truststore`: File with the server truststore + +Apart from that, the following environment variables must be set: + +* `CASSANDRA_KEYSTORE_PASSWORD`: Password for accessing the keystore. +* `CASSANDRA_TRUSTSTORE_PASSWORD`: Password for accessing the truststore. +* `CASSANDRA_INTERNODE_ENCRYPTION`: Sets the type of encryption between nodes. The default value is `none`. Can be set to `all`, `none`, `dc` or `rack`. +* `CASSANDRA_CLIENT_ENCRYPTION`: Enables client-server encryption. The default value is `false`. + +## Logging + +The Bitnami Apache Cassandra Docker image sends the container logs to the `stdout`. To view the logs: + +```console +docker logs cassandra +``` + +or using Docker Compose: + +```console +docker-compose logs cassandra +``` + +You can configure the containers [logging driver](https://docs.docker.com/engine/admin/logging/overview/) using the `--log-driver` option if you wish to consume the container logs differently. In the default configuration docker uses the `json-file` driver. + +## Maintenance + +### Upgrade this image + +Bitnami provides up-to-date versions of Apache Cassandra, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. + +#### Step 1: Get the updated image + +```console +docker pull bitnami/cassandra:latest +``` + +or if you're using Docker Compose, update the value of the image property to +`bitnami/cassandra:latest`. + +#### Step 2: Stop and backup the currently running container + +Stop the currently running container using the command + +```console +docker stop cassandra +``` + +or using Docker Compose: + +```console +docker-compose stop cassandra +``` + +Next, take a snapshot of the persistent volume `/path/to/cassandra-persistence` using: + +```console +rsync -a /path/to/cassandra-persistence /path/to/cassandra-persistence.bkp.$(date +%Y%m%d-%H.%M.%S) +``` + +#### Step 3: Remove the currently running container + +```console +docker rm -v cassandra +``` + +or using Docker Compose: + +```console +docker-compose rm -v cassandra +``` + +#### Step 4: Run the new image + +Re-create your container from the new image. + +```console +docker run --name cassandra bitnami/cassandra:latest +``` + +or using Docker Compose: + +```console +docker-compose up cassandra +``` + +## Notable Changes + +## 3.11.10-debian-10-r81 Split branch 3 + +* Branch 3 has been split into branch 3.0 and 3.11 mirroring the upstream Apache Cassandra repo. + +### 3.11.4-debian-9-r188 and 3.11.4-ol-7-r201 + +* Decrease the size of the container. The configuration logic is now based on Bash scripts in the `rootfs/` folder. + +### 3.11.3-r129 + +-The Apache Cassandra container now adds the possibility to inject custom initialization scripts by mounting cql and sh files in `/docker-entrypoint-initdb.d`. See [this section](#initializing-with-custom-scripts) for more information. + +### 3.11.2-r22 + +* The Apache Cassandra container has been migrated to a non-root user approach. Previously the container ran as the `root` user and the Apache Cassandra daemon was started as the `cassandra` user. From now on, both the container and the Apache Cassandra daemon run as user `1001`. As a consequence, the data directory must be writable by that user. You can revert this behavior by changing `USER 1001` to `USER root` in the Dockerfile. + +## Using `docker-compose.yaml` + +Please be aware this file has not undergone internal testing.
