Reduce Support Effort Of Low Free Disk Issues

When you hand over developers new VM(s), or when you have just created a critical env for your team, remember to be prepared for low disk issues.

If you don’t, it will bite you sooner or later. More annoying, it usually come out as a recurring issue. Evaluating the total support effort, we might get a much bigger number than we thought. Are you feeling the same, my friend?
So how we can make low disk issues less likely to happen? And when it does happen, how we can resolve it faster with less impact?

Verify Docker Images Build By Docker-In-Docker

Using Docker, deployments are more reliable and faster than ever. But how about the docker images build? Containers don’t have any silver bullets. It shifts installation instability from deployment cycle to image build cycle.

I would expect a general solution for the verification of all docker images build. And it should work across different projects. This means less time and effort. Certainly, save money!

Use Nmap To Automate Insecure Ports Check

While go cloud is a prevailing trend, security is something we can’t afford to ignore. People hate malicious access. Periodically check all widely open TCP Ports is one good practice to secure our system in cloud. Obviously DB ports can’t be exposed to the whole internet. Our internal REST API also need to be protected.

We should make sure firewall is properly configured. What’s more important, we need to be always on top of these security holes with minimum efforts. So let’s automate the audit process of insecure TCP Ports.
