This is a new series assembling links to websites I have found interesting or will have to read. This time:
- Security: Setting up an SSH CA. Of course you’re way beyond logging into servers in our serverless times. This is so 2015. But sometimes there are still reasons where you need shell access, we’re talking about ssh here. Sharing the same key for all users is lame, everything else needs a bit of infrastructure like a Certificate Authority, but this is a complex topic. This hands-on article reveals a solution for this.
- Containers (1): 6 creative ways to solve problems with Linux containers and Docker. Some clever use cases for containers beyond run-of-the-mill approaches.
- Containers (2): Another reason why your Docker containers may be slow. Eventually, your containers are just isolated processes that tussle for the same resources like any other program on your servers. This article gives advice on overcoming typical problems.
- Tools: How to deploy an EFK stack to Kubernetes. Choosing Fluentd instead of Logstash is worth considering; this article shows why and how. (Elastic knows about the greediness of Logstash and developed the various beat tools, but fluentd has other advantages, still.)
