Spring Cloud Config Server无法通过Docker中的ssh连接到git
我已经安装了Spring Cloud Config Server来连接到我们本地的Stash（Atlassian Git）存储库。 自行运行应用程序没有问题。
当我将这个项目包装在一个Docker镜像中并执行它时，它永远不会从存储库中加载configuration。 这是一个例外：

FROM java:8 VOLUME /tmp ADD config-manager-1.0-SNAPSHOT.jar config-manager.jar RUN bash -c 'touch /config-manager.jar' RUN mkdir -p /root/.ssh RUN chmod 700 /root/.ssh ADD id_rsa_acp /root/.ssh/id_rsa RUN chmod 600 /root/.ssh/id_rsa RUN echo -e "Host [MASKED DOMAIN]\n\tStrictHostKeyChecking no\n" >> /root/.ssh/config ENTRYPOINT ["java","-Dspring.profiles.active=docker","-Djava.security.egd=file:/dev/./urandom","-jar","/config-manager.jar"]
请注意，id_rsa_acp文件位于同一目录中的Dockerfile旁边。
问题来自ssh config文件用这个replace运行命令
RUN bash -c 'echo -e "Host [MASKED DOMAIN]\n\tStrictHostKeyChecking no\n" >> /root/.ssh/config >> /root/.ssh/config'
