Kubernetes: How to delete PODs based on age/creation time

由 ☆樱花仙子☆ 提交于 2019-12-09 00:13:27
问题 Is it possible to delete POD in kubernetes based on creation time or age? Example : I would like to delete all PODs which are older than 1 day. These PODs are orphaned , therefore no new PODs will be created. 回答1: This command will delete all PODs older than one day : kubectl get pods -o go-template --template '{{range .items}}{{.metadata.name}} {{.metadata.creationTimestamp}}{{"\n"}}{{end}}' | awk '$2 <= "'$(date -d 'yesterday' -Ins --utc | sed 's/+0000/Z/')'" { print $1 }' | xargs --no-run

How to best utilize Kubernetes/minikube DNS for local development [closed]

由 十年热恋 提交于 2019-12-08 15:07:29
问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed last year . We are switching to using Kubernetes. It is simple to access other deployed services within a k8s deployment via the built in dns. So if I have pod/service named app1 and a pod/service named app2 and app1 needs to call app2, it can just use "app2" and k8s dns works its magic and

Relation between preStop hook and terminationGracePeriodSeconds

由 亡梦爱人 提交于 2019-12-07 18:55:17
问题 Basically I am trying to do is play around with pod lifecycle and check if we can do some cleanup/backup such as copy logs before the pod terminates. What I need : Copy logs/heapdumps from container to a hostPath/S3 before terminating What I tried: I used a preStop hook with a bash command to echo a message (just to see if it works !!). Used terminationGracePeriodSeconds with a delay to preStop and toggle them to see if the process works. Ex. keep terminationGracePeriodSeconds:30 sec (default

How to Debug .Net Core Application Running on Minikube from Visual Studio 2017

由 戏子无情 提交于 2019-12-07 09:00:45
问题 I have made a .Net Core Web Application and deployed it on container running on Minikube VM. I want to debug that app, How can I do it using Visual Studio 2017? 回答1: You can use vsdbg to debug any remote dotnet core process on Linux. Kubernetes Minikube uses Docker underneath and Docker container is in fact something like a Linux VM. I wrote a post about this on Medium.com if you need more details. 来源： https://stackoverflow.com/questions/46361844/how-to-debug-net-core-application-running-on
