1.安装Docker 和 Docker Compose。

一般安装了docker 就会安装docker compose 

敲一下命令查看Docker Compose有没有安装成功。

docker-compose --version

2.创建配置文件compose.yml和.env

找一个目录创建两个文件，名称为compose.yml和.env

将一下文本考入到文件中

compose.yml

volumes:
  mongodb_data: { driver: local }
 
services:
  rocketchat:
    image: registry.rocket.chat/rocketchat/rocket.chat:${RELEASE:-latest}
    restart: always
    labels:
      traefik.enable: "true"
      traefik.http.routers.rocketchat.rule: Host(`${DOMAIN:-}`)
      traefik.http.routers.rocketchat.tls: "true"
      traefik.http.routers.rocketchat.entrypoints: https
      traefik.http.routers.rocketchat.tls.certresolver: le
    environment:
      MONGO_URL: "${MONGO_URL:-\
        mongodb://${MONGODB_ADVERTISED_HOSTNAME:-mongodb}:${MONGODB_INITIAL_PRIMARY_PORT_NUMBER:-27017}/\
        ${MONGODB_DATABASE:-rocketchat}?replicaSet=${MONGODB_REPLICA_SET_NAME:-rs0}}"
      MONGO_OPLOG_URL: "${MONGO_OPLOG_URL:\

      ROOT_URL: ${ROOT_URL:-http://localhost:${HOST_PORT:-3000}}
      PORT: ${PORT:-3000}
      DEPLOY_METHOD: docker
      DEPLOY_PLATFORM: ${DEPLOY_PLATFORM:-}
      REG_TOKEN: ${REG_TOKEN:-}
    depends_on:

    expose:

    ports:
      - "${BIND_IP:-0.0.0.0}:${HOST_PORT:-3000}:${PORT:-3000}"
 
  mongodb:
    image: docker.io/bitnami/mongodb:${MONGODB_VERSION:-5.0}
    restart: always
    volumes:
      - mongodb_data:/bitnami/mongodb
    environment:
      MONGODB_REPLICA_SET_MODE: primary

.env

### Rocket.Chat configuration
 
# Rocket.Chat version
# see:- https://github.com/RocketChat/Rocket.Chat/releases
#RELEASE=
# MongoDB endpoint (include ?replicaSet= parameter)
#MONGO_URL=
# MongoDB endpoint to the local database
#MONGO_OPLOG_URL=
# IP to bind the process to
#BIND_IP=
# URL used to access your Rocket.Chat instance
#ROOT_URL=
# Port Rocket.Chat runs on (in-container)
#PORT=
# Port on the host to bind to
#HOST_PORT=
 
### MongoDB configuration
# MongoDB version/image tag
#MONGODB_VERSION=
# See:- https://hub.docker.com/r/bitnami/mongodb
 
### Traefik config (if enabled)
# Traefik version/image tag
#TRAEFIK_RELEASE=
# Domain for https (change ROOT_URL & BIND_IP accordingly)
#DOMAIN=
# Email for certificate notifications
#LETSENCRYPT_EMAIL=

上述文件可以不进行修改，需要进行自定义配置时才进行修改，修改后将前面的井号去掉（#），一下是一些修改的例子

1.在.env文件中修改RELEASE可以指定安装的版本，这个最好指定一下，最新的版本可能不是很稳定可以选一个次新的版本例如：

RELEASE=6.2.11

2.在.env文件中修改MONGO_URL可以将自己的MONGO数据库接入到rocket chat如：

MONGO_URL=mongodb://<user>:<pass>@host1:27017,host2:27017,host3:27017/<databaseName>?replicaSet=<replicaSet>&ssl=true&authSource=admin

不修改则会自动安装新的MONGO数据库镜像。

3.修改ROOT_URL可以修改为你自己的ip地址如：

​
ROOT_URL=http://localhost:3000

3.拉取镜像并开启服务

将命令行的当前目录转到创建文件的位置（即和compose.yml和.env文件同目录），并执行一下命令即可完成安装

docker compose up -d

完成后可以打开本地的3000端口查看部署结果，打开http://localhost:3000

4.本地配置nginx将3000端口映射到公网，并配置为https服务

该配置请自行配置，没有外网ip的可以购买某些平台的端口映射服务，https可以找阿里云申请证书
