Re: install questions (on AWS)
Hi, I looked at [4], and it isn't clear about which host / hosts the EIPs will get mapped to. This makes a difference in the cost of my solution. If I have 10 EIPs and 10 hosts, and I map one per host, the ip addresses are free. But if OpenShift needs me to map them all to one host, I need to pay for 9 (because the first one is free). How does this work? To be clear, I'm asking about v3. I'll ask this and other v4 questions in the forum you pointed me to. Thanks, Marvin On Wed, Mar 6, 2019 at 3:53 PM W.

Control IOPS storage in openshift
Hi guys. the question that i have is about IOPS in storage. Imagine this scenario: i'm using cinder(openstack) to create volumes to openshift. in cider i can limit IOPS [1] for write and reads. my question is, are there some way to control IOPS storage in openshift ? I saw that is possible to storage from aws but i didn't find for Cinder or Ceph. Best regards Sérgio [1] https://docs.openstack.org/cinder/latest/admin/blockstorage-basic-volume-qos.html ___ users mailing list users@lists.openshift.redhat.com http://lists.openshift.redhat.com/openshiftmm/listinfo/users

install questions (on AWS)
Hi, Firstly - is this the right place to ask questions pertaining to the v4 developer preview? If not, would appreciate a pointer to the right place please. I have questions pertaining to how one would install on AWS (v4 or v3). AWS charges for Elastic IP's that are not mapped to a running EC2 instance, or additional elastic IP's (more than one) mapped to a EC2 instance. I know how many elastic IPs I need for routes, but I'm not sure how these IPs need to be assigned. Do I say that all those IP addresses are going to be assigned to the host running the SDN (openvswitch?) components? Or do I distribute them across the worker nodes? Do I need an elastic ip address for kube-dns (and if so, which host is that on - the master)? If I need to enable https end-user traffic, will I need to install CA (but private CA) cert generating components, or does Openshift have the capability to dynamically generate the certificates for my routes?

Re: Having trouble with "oc explain" syntax
A template is a list of "any object". So the things you put as items in the objects array are the things you would "oc explain deployment|service|secret|*" on On Wed, Mar 6, 2019 at 12:16 PM Just Marvin < marvin.the.cynical.ro...@gmail.com> wrote: > Clayton, > > Appreciate the quick response.

Re: Having trouble with "oc explain" syntax
Clayton, Appreciate the quick response. Is there an alternative for getting information on the structure of a template? Most of the interesting content in a template is under that "objects" tree. For example, template.objects.spec doesn't work either. I tried "oc explain object" but the tool wasn't too happy about that.

Re: Having trouble with "oc explain" syntax
Objects is opaque (literally "any object") so you can't get open api metadata on it.

Having trouble with "oc explain" syntax
Hi, The structure of a template is --> objects --> metadata . "oc explain template.objects" shows me good results, though the output of it doesn't show a metadata child. "oc explain template.objects.metadata" fails saying "error: field "metadata" does not exist". What is the right syntax for dealing with the "objects" array?
