我的目标是比较我的golang应用程序的两个docker解决方案:
使用ubuntu作为基本图像
以高亮:阿尔卑斯山为基础图像
我的Dockerfile非常直截了当,类似于:
FROM ubuntu:20.04
# FROM golang:alpine for alpine based images
# myApp binary is pre-built before running docker build
COPY bin/myApp app/myApp
COPY myApp-config.json app/myApp-config.json

我在一台主机上运行docker容器,所有这些容器都在一个网桥网络中。我正在使用rsync等工具在它们之间传输数据。我有CamelCase容器名称。例如,我可以通过REST从Java应用程序连接到具有这些名称的其他运行容器,但是rsync/ssh无法处理它们。
root@container-id:/# rsync -av /sourceFolder user@CamelCaseContainer:/targetFolder
ssh: Could not resolve hostname camelcasecontainer: Name or service not known

我的ISP使用L2TP将用户连接到互联网。我在Windows上有一个工作连接,现在我试图将它克隆到一个Ubuntu上。当然,我得到间歇性的“服务启动失败”和“服务意外停止”错误,就像其他人一样。
