mariusv / kops-dns-controller-patch
Created Jul 4, 2019
Patch kops DNS controller to `--watch-ingress=true`
View kops-dns-controller-patch
Steps for the workaround:
Check the yaml of current deployment for the dns-controller. Here you will find the path to the --watch-ingress setting.
`kubectl get deployment -n kube-system dns-controller -o yaml`
Use the path and make a patch of the deployment. I think the path here will work for most.
```kubectl patch deployment -n kube-system dns-controller --type='json' -p='[{"op": "replace", "path": "/spec/template/spec/containers/0/command/1", "value":"--watch-ingress=true"}]'```

DevOps started out as "Agile Systems Administration". In 2008, Andrew Shafer did a talk called "Agile Infrastucture" addressing issues around involving more of the company in the same disciplines as programmers.

In 2009, Patrick Debois created "DevOpsDays" conference to help to bring it to light. However, it wouldn't begin to trend until about 2010, when people would begin to describe it as a standalone discipline.

Today, DevOps goes beyond just developers, systems administration and infrastructure, its about [dev, ops, agile, cloud, open source and business](https://blogs.the451group.com/opensource/2010/03/03/devops-mixing-dev-ops-agile-cloud-open-source-and-busi

mariusv / remove-docker-containers.md
Created Nov 6, 2017 — forked from ngpestelos/remove-docker-containers.md
How to remove unused Docker containers and images
View remove-docker-containers.md
  1. Delete all containers

     $ docker ps -q -a | xargs docker rm
    

-q prints only the container IDs -a prints all containers

Notice that it uses xargs to issue a remove container command for each container ID

  1. Delete all untagged images

Check if your server was compromised with the rootkit which leaves a backdoor on the system and gains the full root access to Linux-based servers.
