fiware/mintaka Docker 镜像 - 轩辕镜像

Mintaka

Mintaka是NGSI-LD时间检索API的实现，它依赖Orion-LD上下文代理提供底层数据库。NGSI-LD规范是一个动态发展的文档，最新的Orion-LD测试版发布几乎已完整支持1.3.1版ETSI规范。更多信息请参考其GitHub仓库。

标签

所有镜像通过CI流水线创建，包含以下类型的标签：

每个标签存在3个版本：

• 无后缀：默认镜像，基于gcr.io/distroless/java:11
• -distroless后缀：基于gcr.io/distroless/java:11的镜像，例如0.0.1-distroless
• -rhel后缀：基于Redhat认证基础镜像openjdk-11-rhel7的镜像，例如0.0.1-rhel

使用方法

Mintaka依赖由Orion-LD填充数据的TimescaleDB。以下是示例部署配置，更多选项请查看GitHub：

yaml
version: "3.5"
services:
  # Orion是上下文代理
  orion-ld:
    image: fiware/orion-ld
    hostname: orion
    # 有时初始启动可能因Timescale的特殊行为而失败
    restart: always

      - ORIONLD_MONGO_HOST=mongo-db
    depends_on:
      - mongo-db

    command: -logLevel DEBUG
    healthcheck:
      test: curl --fail -s [***] || exit 1
      interval: 30s
      retries: 15


  # 数据库

    command: --nojournal
    volumes:

    healthcheck:
      test: |
        host=`hostname --ip-address || echo '127.0.0.1'`;
        mongo --quiet $host/test --eval 'quit(db.runCommand({ ping: 1 }).ok ? 0 : 2)' && echo 0 || echo 1
      interval: 30s

  timescale:
    image: timescale/timescaledb-postgis:latest-pg12
    hostname: timescale
    healthcheck:
      test: [ "CMD-SHELL", "pg_isready -U orion" ]
      interval: 15s
      timeout: 15s
      retries: 15
      start_period: 60s
    environment:
      - POSTGRES_USER=orion
