使用Config-map parser构建WSO2 MI Docker镜像的集群连接问题

问题概述 #

使用Config-map parser构建WSO2 MI 4.0.0 Docker镜像时，Bitbucket构建流程要求必须复制仓库内所有文件（包含metadata_config.properties），否则构建失败。已在deployment.toml中配置集群协调数据库信息，但构建完成后的镜像无法连接集群。本地环境中，注释掉Dockerfile里复制metadata_config.properties的语句后，构建并运行的镜像可正常工作，此时metadata_config文件会自动生成不同的ID。

所用Dockerfile配置 #
