## Configuration
The configuration can easily be setup with the Bitnami Apache ZooKeeper Docker image using the following environment variables:
### Environment variables
* `ZOO_PORT_NUMBER`: Apache ZooKeeper client port. Default: **2181**
* `ZOO_SERVER_ID`: ID of the server in the ensemble. Default: **1**
* `ZOO_TICK_TIME`: Basic time unit in milliseconds used by Apache ZooKeeper for heartbeats. Default: **2000**
* `ZOO_PRE_ALLOC_SIZE`': Block size for transaction log file. Default: **65536**
* `ZOO_SNAPCOUNT`: The number of transactions recorded in the transaction log before a snapshot can be taken (and the transaction log rolled). Default: **100000**
* `ZOO_INIT_LIMIT`: Apache ZooKeeper uses to limit the length of time the Apache ZooKeeper servers in quorum have to connect to a leader. Default: **10**
* `ZOO_SYNC_LIMIT`: How far out of date a server can be from a leader. Default: **5**
* `ZOO_MAX_CNXNS`: Limits the total number of concurrent connections that can be made to an Apache ZooKeeper server. Setting it to 0 entirely removes the limit. Default: **0**
* `ZOO_MAX_CLIENT_CNXNS`: Limits the number of concurrent connections that a single client may make to a single member of the Apache ZooKeeper ensemble. Default: **60**
* `ZOO_4LW_COMMANDS_WHITELIST`: List of whitelisted [4LW](https://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_4lw) commands. Default: **srvr, mntr**
* `ZOO_SERVERS`: Comma, space or semi-colon separated list of servers. Example: zoo1:2888:3888,zoo2:2888:3888 or if specifying server IDs zoo1:2888:3888::1,zoo2:2888:3888::2. Default: No defaults.

When you start the Apache ZooKeeper image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the `docker run` command line. If you want to add a new environment variable:
* For manual execution add a -e option with each variable and value:
```console
docker run --name zookeeper -e ZOO_SERVER_ID=1 bitnami/zookeeper:latest
```
or modify the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/zookeeper/docker-compose.yml) file present in this repository:
* For docker-compose add the variable name and value under the application section in the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/zookeeper/docker-compose.yml) file present in this repository:
