Mintaka

Mintaka是NGSI-LD时间检索API的实现，它依赖https://github.com/FIWARE/context.Orion-LD%E6%8F%90%E4%BE%9B%E5%BA%95%E5%B1%82%E6%95%B0%E6%8D%AE%E5%BA%93%E3%80%82NGSI-LD%E8%A7%84%E8%8C%83%E6%98%AF%E4%B8%80%E4%B8%AA%E5%8A%A8%E6%80%81%E5%8F%91%E5%B1%95%E7%9A%84%E6%96%87%E6%A1%A3%EF%BC%8C%E6%9C%80%E6%96%B0%E7%9A%84Orion-LD%E6%B5%8B%E8%AF%95%E7%89%88%E5%8F%91%E5%B8%83%E5%87%A0%E4%B9%8E%E5%B7%B2%E5%AE%8C%E6%95%B4%E6%94%AF%E6%8C%811.3.1%E7%89%88ETSI%E8%A7%84%E8%8C%83%E3%80%82%E6%9B%B4%E5%A4%9A%E4%BF%A1%E6%81%AF%E8%AF%B7%E5%8F%82%E8%80%83%E5%85%B6https://github.com/FIWARE/mintaka%E3%80%82

标签

所有镜像通过https://github.com/FIWARE/mintaka/tree/main/.github/workflows%E5%88%9B%E5%BB%BA%EF%BC%8C%E5%8C%85%E5%90%AB%E4%BB%A5%E4%B8%8B%E7%B1%BB%E5%9E%8B%E7%9A%84%E6%A0%87%E7%AD%BE%EF%BC%9A

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
