+# ClickHouse packaged by Bitnami
+
+## What is ClickHouse?
+
+> ClickHouse is an open-source column-oriented OLAP database management system. Use it to boost your database performance while providing linear scalability and hardware efficiency.
+
+[Overview of ClickHouse](https://clickhouse.com/)
+
+Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.
+
+## TL;DR
+
+```console
+$ docker run --name clickhouse bitnami/clickhouse:latest
+```
+
+### Docker Compose
+
+```console
+$ curl -sSL https://raw.githubusercontent.com/bitnami/containers/main/bitnami/clickhouse/docker-compose.yml > docker-compose.yml
+$ docker-compose up -d
+```
+
+## Why use Bitnami Images?
+
+* Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
+* With Bitnami images the latest bug fixes and features are available as soon as possible.
+* Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
+* All our images are based on [minideb](https://github.com/bitnami/minideb) a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
+* All Bitnami images available in Docker Hub are signed with [Docker Content Trust (DCT)](https://docs.docker.com/engine/security/trust/content_trust/). You can use `DOCKER_CONTENT_TRUST=1` to verify the integrity of the images.
+* Bitnami container images are released on a regular basis with the latest distribution packages available.
+
+## How to deploy ClickHouse in Kubernetes?
+
+Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the [Bitnami ClickHouse Chart GitHub repository](https://github.com/bitnami/charts/tree/master/bitnami/clickhouse).
+
+Bitnami containers can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

+
+## Get this image
+
+The recommended way to get the Bitnami ClickHouse Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/clickhouse).
+
+```console
+$ docker pull bitnami/clickhouse:latest
+```
+
+To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/clickhouse/tags/) in the Docker Hub Registry.
+
+```console
+$ docker pull bitnami/clickhouse:[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/clickhouse` path. If the mounted directory is empty, it will be initialized on the first run.
+
+```console
+$ docker run \
+    --volume /path/to/clickhouse-persistence:/bitnami/clickhouse \
+    --env ALLOM_EMPTY_PASSWORD=false \
+    bitnami/clickhouse:latest
+```
+
+You can also do this with a minor change to the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/clickhouse/docker-compose.yml) file present in this repository:
+
+```console
+clickhouse:
+  ...
+  volumes:
+    - /path/to/clickhouse-persistence:/bitnami/clickhouse
+  ...
+```
+
+## 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
+
+In this example, we will create a ClickHouse 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 my-network --driver bridge
+```
+
+#### Step 2: Launch the ClickHouse container within your network
+
+Use the `--network <NETWORK>` argument to the `docker run` command to attach the container to the `my-network` network.
+
+```console
+$ docker run -d --name clickhouse-server \
+  --network my-network \
+  --env ALLOW_EMPTY_PASSWORD=yes \
+  bitnami/clickhouse:latest
+```
+
+#### Step 3: Launch your ClickHouse client instance
+
+Finally we create a new container instance to launch the ClickHouse client and connect to the server created in the previous step:
+
+```console
+$ docker run -it --rm \
+    --network my-network \
+    bitnami/clickhouse:latest clickhouse-client --host clickhouse-server
+```
+
+### Using Docker Compose
+
+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 `my-network`. In this example we assume that you want to connect to the ClickHouse server from your own custom application image which is identified in the following snippet by the service name `myapp`.
+
+```yaml
+version: '2'
+
+networks:
+  my-network:
+    driver: bridge
+
+services:
+  clickhouse:
+    image: bitnami/clickhouse:latest
+    environment:
+      - ALLOW_EMPTY_PASSWORD=no
+    networks:
+      - my-network
+  myapp:
+    image: 'YOUR_APPLICATION_IMAGE'
+    networks:
+      - my-network
+```
+
+> **IMPORTANT**:
+>
+> 1. Please update the `YOUR_APPLICATION_IMAGE` placeholder in the above snippet with your application image
+> 2. In your application container, use the hostname `clickhouse` to connect to the ClickHouse server
+
+Launch the containers using:
+
+```console
+$ docker-compose up -d
+```
+
+## Configuration
+
+ClickHouse can be configured via environment variables or using a configuration file (`config.xml`). If a configuration option is not specified in either the configuration file or in an environment variable, ClickHouse uses its internal default configuration.
+
+### Configuration overrides
+
+The configuration can easily be setup by mounting your own configuration overrides on the directory `/bitnami/clickhouse/conf/conf.d` or `/bitnami/clickhouse/conf/users.d`:
+
+```console
+$ docker run --name clickhouse \
+    --volume /path/to/override.xml:/bitnami/clickhouse/conf/conf.d/override.xml:ro \
+    bitnami/clickhouse:latest
+```
+
+or using Docker Compose:
+
+```yaml
+version: '2'
+
+services:
+  clickhouse:
+    image: bitnami/clickhouse:latest
+    volumes:
+      - /path/to/override.xml:/bitnami/clickhouse/conf/override.xml:ro
+```
+
+Check the [official ClickHouse configuration documentation](https://clickhouse.com/docs/en/operations/configuration-files/) for all the possible overrides and settings.
+
+### Initializing a new instance
+
+When the container is executed for the first time, it will execute the files with extensions `.sh` located at `/docker-entrypoint-initdb.d`. For scripts to be executed every time the container starts, use the `/docker-entrypoint-startdb.d` folder.
+
+In order to have your custom files inside the docker image you can mount them as a volume.
+
+### Setting the admin password on first run
+
+The admin user and password can easily be setup with the Bitnami ClickHouse Docker image using the following environment variables:
+
+ - `CLICKHOUSE_ADMIN_USER`: The database admin user. Defaults to `default`.
+ - `CLICKHOUSE_ADMIN_PASSWORD`: The database admin user password. No defaults.
+
+Passing the `CLICKHOUSE_ADMIN_PASSWORD` environment variable when running the image for the first time will set the password of the `CLICKHOUSE_ADMIN_USER` user to the value of `CLICKHOUSE_ADMIN_PASSWORD`.
+
+```console
+$ docker run --name clickhouse -e CLICKHOUSE_ADMIN_PASSWORD=password123 bitnami/clickhouse:latest
+```
+
+or by modifying the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/clickhouse/docker-compose.yml) file present in this repository:
+
+```yaml
+services:
+  clickhouse:
+  ...
+    environment:
+      - CLICKHOUSE_ADMIN_PASSWORD=password123
+  ...
+```
+
+### Changing the default ports
+
+ClickHouse default ports can be changed using the following environment variables:
+
+- `CLICKHOUSE_HTTP_PORT`: HTTP port. Defaults to `8123`.
+- `CLICKHOUSE_TCP_PORT`: TCP port. Defaults to `9000`.
+- `CLICKHOUSE_MYSQL_PORT`: MySQL port. Defaults to `9004`.
+- `CLICKHOUSE_POSTGRESQL_PORT`: PostgreSQL port. Defaults to `9005`.
+- `CLICKHOUSE_INTERSERVER_HTTP_PORT`: Inter-server HTTP port. Defaults to `9009`.
+
+### Allowing empty passwords
+
+By default the ClickHouse image expects all the available passwords to be set. In order to allow empty passwords, it is necessary to set the `ALLOW_EMPTY_PASSWORD=yes` env variable. This env variable is only recommended for testing or development purposes. We strongly recommend specifying the `CLICKHOUSE_ADMIN_PASSWORD` for any other scenario.
+
+```console
+$ docker run --name clickhouse --env ALLOW_EMPTY_PASSWORD=yes bitnami/clickhouse:latest
+```
+
+or by modifying the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/clickhouse/docker-compose.yml) file present in this repository:
+
+```yaml
+services:
+  clickhouse:
+  ...
+    environment:
+      - ALLOW_EMPTY_PASSWORD=yes
+  ...
+```
+
+## Logging
+
+The Bitnami ClickHouse Docker image sends the container logs to `stdout`. To view the logs:
+
+```console
+$ docker logs clickhouse
+```
+
+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 ClickHouse, 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/clickhouse:latest
+```
+
+or if you're using Docker Compose, update the value of the image property to `bitnami/clickhouse:latest`.
+
+#### Step 2: Stop and backup the currently running container
+
+Stop the currently running container using the command
+
+```console
+$ docker stop clickhouse
+```
+
+or using Docker Compose:
+
+```console
+$ docker-compose stop clickhouse
+```
+
+Next, take a snapshot of the persistent volume `/path/to/clickhouse-persistence` using:
+
+```console
+$ rsync -a /path/to/clickhouse-persistence /path/to/clickhouse-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)
+```
+
+#### Step 3: Remove the currently running container
+
+```console
+$ docker rm -v clickhouse
+```
+
+or using Docker Compose:
+
+```console
+$ docker-compose rm -v clickhouse
+```
+
+#### Step 4: Run the new image
+
+Re-create your container from the new image.
+
+```console
+$ docker run --name clickhouse bitnami/clickhouse:latest
+```
+
+or using Docker Compose:
+
+```console
+$ docker-compose up clickhouse
+```
