在 Docker 容器中運行 Elasticsearch 和 Cerebro

接上篇：Elasticsearch 7.x 的安裝與簡單配置（阿里雲Ubuntu）

系統環境

• 操作系統：Ubuntu 18.04 LTS（阿里雲）
• 系統IP

# 內網，私有地址
172.內.內.內
# 外網，公有地址
112.外.外.外

• Elasticsearch 版本：7.2
• Docker 版本：18.09

安裝

• cerebro github: https://github.com/lmenezes/c...
• 安裝 docker

$ sudo apt install docker
# 將當前用戶加入 docker 組，避免 root 權限運行 docker 命令
$ sudo usermod -aG docker ${USER}
$ docker --version
Docker version 18.09.7, build 2d0083d

• 安裝 docker.io

$ sudo apt install docker.io

• 安裝 docker-compose

$ sudo apt install docker-compose
$ docker-compose --version
docker-compose version 1.17.1, build unknown

配置 docker 鏡像加速器

• 阿里雲控制檯 -> 產品與服務 -> 彈性計算 -> 容器鏡像服務

創建並啓動容器

• 將 docker-compose.yaml 保持到 Ubuntu 本地目錄，內容如下（https://github.com/geektime-g...）

• 在 docker-compose.yaml 所在目錄運行以下命令，創建並啓動容器

$ docker-compose up
