问题 Kubernetes seems to be all about deploying containers to a cloud of clusters. What it doesn't seem to touch is development and staging environments (or such). During development you want to be as close as possible to production environment with some important changes: Deployed locally (or at least somewhere where you and only you can access ) Use latest source code on page refresh (supposing its a website; ideally page auto-refresh on local file save which can be done if you mount source code

问题 I set up openshift V3 all-in-one on a VM in the cloud so how can I contact it as the address is private and internal. I think I have to start Vagrand with some magic parameters but I haven't clue about them. Thanks 回答1: When testing Openshift, I deployed the all in one VM in an Openstack instance. To be able to access Openshift, I had to change master-config.yaml configuration (which in the VM is located in /var/lib/origin/openshift.local.config/master/master-config.yaml) Changing all

问题 Is it possible to write a scheduler rule to schedule builds on a specific node label (e.g. role=builder )? I'm struggling to understand how the schedular rules match pod labels (e.g. buildconfig=web to node types). 回答1: It is not possible today without adding a custom scheduler extension.

问题 I'm trying to compile openshift origin source on my raspberry pi 3 but it keeps timing out. The tutorial I'm following is from here Reason I'm doing this is because I get the error ./oc: cannot execute binary file: Exec format error when I download the file directly from here and use it. So can anyone tell me what I have to do to make this work or how I fix the errors? With openshift 2 being discontinued soon, I cannot access my application with rhc anymore (which works fine on my RPi3). 回答1:

问题 can we use same NFS persistent volume for multiple pods in openshift v3.1. because what I noticed is when I mount the same persistent volumes to multiple pods, all data inside mounted directory of container gets replaced by NFS volume directory of server. How to make sure that NFS volume has data from multiple pods. And pods only has their data, not all data from the PV? thanks in advance! 回答1: NFS persistent volumes will be the same across multiple pods. You can always use the pod name as an

问题 I have configured my Gitlab CI pipelines so that they build an OCI image with Docker-in-Docker and upload it to Gitlab's own registry. Now, I want to deploy images built in my CI pipelines to OpenShift Origin. All images in the registry are tagged with $CI_COMMIT_SHORT_SHA (i.e.: I do not use "latest"). How can I do that? This is what I have tried so far: before_script: - oc login --server="$OPENSHIFT_SERVER" --token="$OPENSHIFT_TOKEN" - oc project myproject script: - oc tag registry.gitlab

问题 Would be possible, when migrating from Openshift 2 to 3, to keep the xxx.rhcloud.com url? Anybody knows if Red Hat is providing some solution? O maybe some kind of redirection would work? Thanks in advance. 回答1: Confirmed by Openshift Support: "Unfortunately, we are unable to provide the same URLs that you have used previously. You would have to recompile your applications with new URLs following a migration." 来源： https://stackoverflow.com/questions/45923453/openshift-public-url-app-migration
