You can view the [list of available versions](https://hub.docker.com/r/bitnami/valkey-cluster/tags/) in the Docker Hub Registry. + +```console +docker pull bitnami/valkey-cluster:[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 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 \ + -e ALLOW_EMPTY_PASSWORD=yes + -v /path/to/valkey-cluster-persistence:/bitnami \ + bitnami/valkey-cluster:latest +``` + +You can also do this with a minor change to the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/valkey-cluster/docker-compose.yml) file present in this repository: + +```yaml +valkey-cluster: + ... + volumes: + - /path/to/valkey-cluster-persistence:/bitnami + ... +``` + +## Connecting to other containers + +Using [Docker container networking](https://docs.docker.com/engine/userguide/networking/), a different server running inside a container can easily be accessed by your application containers and vice-versa. + +Containers attached to the same network can communicate with each other using the container name as the hostname. + +### Using the Command Line + +#### Step 1: Create a network + +```console +docker network create valkey-cluster-network --driver bridge +``` + +#### Step 2: Launch the Valkey Cluster container within your network + +Use the `--network ` argument to the `docker run` command to attach the container to the `valkey-cluster-network` network. + +```console +docker run -e ALLOW_EMPTY_PASSWORD=yes --name valkey-cluster-node1 --network valkey-cluster-network bitnami/valkey-cluster:latest +``` + +#### Step 3: Run another containers + +We can launch another containers using the same flag (`--network NETWORK`) in the `docker run` command.

The image will look for `/opt/bitnami/valkey/mounted-etc/overrides.conf`.

command like the following to initiate the cluster: + +```console +valkey-cli --cluster create node1:port node2:port --cluster-replicas 1 --cluster-yes +``` + +Where you can add all the `node:port` that you want. The `--cluster-replicas` parameters indicates how many replicas you want to have for every master. + +### Cluster Initialization Troubleshooting + +Depending on the environment you're deploying into, you might run into issues where the cluster initialization is not completing successfully. One of the issue is related to the DNS lookup of the valkey nodes performed during cluster initialization. By default, this DNS lookup is performed as soon as all the valkey nodes reply to a successful ping. +However, in some environments such as Kubernetes, it can help to wait some time before performing this DNS lookup in order to prevent getting stale records. To this end, you can increase `VALKEY_CLUSTER_SLEEP_BEFORE_DNS_LOOKUP` to a value around `30` which has been found to be good in most cases. + +### Securing Valkey Cluster traffic + +Valkey adds the support for SSL/TLS connections, to enable this optional feature, you may use the aforementioned `VALKEY_TLS_*` environment variables to configure the application. + +When enabling TLS, conventional standard traffic is disabled by default. However this new feature is not mutually exclusive, which means it is possible to listen to both TLS and non-TLS connection simultaneously. To enable non-TLS traffic, set `VALKEY_TLS_PORT_NUMBER` to another port different than `0`. + +1. Using `docker run` + + ```console + $ docker run --name valkey-cluster \ + -v /path/to/certs:/opt/bitnami/valkey/certs \ + -v /path/to/valkey-cluster-persistence:/bitnami \ + -e ALLOW_EMPTY_PASSWORD=yes \ + -e VALKEY_TLS_ENABLED=yes \ + -e VALKEY_TLS_CERT_FILE=/opt/bitnami/valkey/certs/valkey.crt \ + -e VALKEY_TLS_KEY_FILE=/opt/bitnami/valkey/certs/valkey.key \ + -e VALKEY_TLS_CA_FILE=/opt/bitnami/valkey/certs/valkeyCA.crt \ + bitnami/valkey-cluster:latest + ``` + +2.

If you want to modify the default strategy, you can configure it through the `VALKEY_RDB_POLICY` parameter. Here is a demonstration of modifying the default persistence strategy + +1. Using `docker run` + + ```console + $ docker run --name valkey-cluster \ + -v /path/to/valkey-cluster-persistence:/bitnami \ + -e ALLOW_EMPTY_PASSWORD=yes \ + -e VALKEY_RDB_POLICY_DISABLED=no + -e VALKEY_RDB_POLICY="900#1 600#5 300#10 120#50 60#1000 30#10000" + bitnami/valkey-cluster:latest + ``` + +2.

To view the logs: + +```console +docker logs valkey-cluster +``` + +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.
