CentOS 7.2 cloud images for ppc64le
by Xiandong Meng 14 Jun '16

14 Jun '16

Hi all, I noticed that there are centos 7 cloud images for x86. But i did not find the cloud images for ppc64le. Are there any work on it within this community? Or is there any plan to work on it? Regards, Xiandong Meng <mengxiandong(a)gmail.com> mengxiandong(a)gmail.com

Curating containers
by Karanbir Singh 05 Apr '16

05 Apr '16

hi, Yesterday a few of us met for a face to face walk through of the CentOS Container Pipeline we've been talking about. The aim was to rescope the upstream projects we can lean on, share code with, and help - and then find the glue pieces that could bring this code base together. The larger picture effectively boils down to : - Find the components needed to track code git repos ( either in git.centos.org or elsewhere ) - Find the components needed to now build that code, containerise the code, push it through a test process, and then deliver the containers either locally into a centos transitional container registry, or to a CDN like wider centos registry or if the user so desires, to a third part registry ( provided a good process can be find to handle the credentials needed ). - We'd want to use this pipeline both internally, for the CentOS Linux components ( eg. a LAMP container from CentOS Linux 7 ), for SIG components via cbs output ( eg. SCLo SIG folks shipping containers for their content ), as well as open this up via a trivial UI, for anyone in the community who'd like to come and consume this pipeline. the key piece that we didnt have clarity on was the orchestration and glue that could bind the various software components. Vaclav Pavlin, brought up that we might be able to use openshift templates in order to get the job runs done - if the input for the templates could be derived from the cccp-index, either via the jjb work already done, or writing a new filter into JJB, we might be able to execute a fairly scaleable solution without needing to own any piece of the over all code. Additionally, there is a fair interest from the Fedora team ( ie Adam! ) working on the same problem in their space, mostly consuming the identical code stack, within and for their infra, their constraints and aims. Over the coming days we are going to try and work though PoC's, get some infra setup and trial running through some of the user stories we want to execute on. Finally, a quick shout out to everyone for coming together at pretty much the last minute adhoc meeting - Fabian Arrotin, Brian Stinson, Christoph Goern, Vaclav Pavlin, Aaron Weitekamp, Tomas Tomecek, Adam Miller, Dusty Mabe, Honza Horak, Radek Vokal as well as Tim Waugh, Bama Charan and Mohammed Zeeshan for dialing into the meeting. And to everyone else, want to build containers with us ? come talk to us - we'd love to make sure we include as many user stories to get great scope before we start implementing bits. regards -- Karanbir Singh, Project Lead, The CentOS Project +44-207-0999389 | http://www.centos.org/ | twitter.com/CentOS GnuPG Key : http://www.karan.org/publickey.asc

[RFE] subscription-manager in CentOS6
by Baptiste Agasse 04 Apr '16

04 Apr '16

Hi, I tried to speak about this to Johnny at the end of the last CentOS Dojo in Brussels, but he have to go. There is any chance that you to include subscription-manager in CentOS 6 ? We use foreman/katello, all work out of the box for centos 7 but it's not easy to manage additional installation repos in foreman/katello to manage that in one generic kickstart template for our deployments (multiple DCs, with multiple repos mirrors per locations...). As i see in the git repo of CentOS 7 [1], there is only few changes, like debranding. I see that redhat provides SRPMS for subscription-manager as well for RHEL6 [2] and versions of subscription-manager are are not so far from each other: RHEL 7 / CentOS 7 : subscription-manager 1.15.9 RHEL 6 : subscription-manager 1.14.10 I didn't take a look deeper at this time, but if there is any chance that you decide to include subscription-manager in CentOS 6 base repo and installation tree like in CentOS 7, i can take a look deeper to see if patches that are made for C7 are compatible with RHEL 6 subscription manager, and if not, backport them to c6. Have a nice day. Regards. [1] https://git.centos.org/tree/rpms!subscription-manager.git/refs!heads!c7 [2] ftp://ftp.redhat.com/redhat/linux/enterprise/6Server/en/os/SRPMS/ -- Baptiste

Problem installing golang.x86_64 with virt7-docker-common-candidate.
by centos-devel 02 Apr '16

02 Apr '16

First off- Thanks to all for reading and especially to Jan for responding so helpfully. So I realised that I could maybe make some progress by telling yum to ignore go version 1.5 from virt7-testing and just install the older 1.4 branch from extras. [root@vm139 admin]# yum --disablerepo base --disablerepo virt7-testing --skip-broken install golang Of course that just worked. :-) Having reread Jans first email again, > > godep go run make_secret.go -crt /tmp/nginx.crt -key /tmp/nginx.key > > > /tmp/secret.json > > godep: No Godeps found (or in any parent directory) > > make: *** [secret] Error 1 > > It says you are running godep in a directory where there is no Godeps > file. Once the binary is compiled, you don't need golang compiler. and read a bit more about godeps, I thought I would try without it to see if I could get past that error. So I just edited the Makefile: https://github.com/kubernetes/kubernetes/blob/release-1.2/examples/https-ng… to remove the call to godeps from: godep go run make_secret.go -crt $(CERT) -key $(KEY) > $(SECRET) to: go run make_secret.go -crt $(CERT) -key $(KEY) > $(SECRET) But that just spews errors that go can't find the dependencies it needs. well, DUH! I suppose those are meant to be listed in the Godeps file that godeps is complaining that it cannot find. As I said - this is new to me as I have not (yet) programmed in go. What do other people think? Does anyone more knowlegable than me about Kubernetes or Go have any suggestions? Perhaps I should submit a bug to github-kubernetes and move on? Thanks again to all for reading and especially to Jan for responding so helpfully. Colin. p.s. What I learned: Using CBS virt7-testing to provide docker and kubernetes Package: golang-1.5.1-1.el7.x86_64 will not install because it Requires: golang-src = 1.5.1-1.el7

centos git web front-end
by Phil Wyett 31 Mar '16

31 Mar '16

Hi all, What if any plans are in the pipeline for improving the web front-end of git.centos.org? Current issues: * Slow. * No search as page claims: none of your repositories are configured for Lucene indexing * Clicking on the 'repositories' link, hangs firefox because of how many entries are being listed by default. Could this be a static page with alphanumeric index that a user can click on depending on first character of package they wish to find? Regards Phil

Problem installing golang.x86_64 with virt7-docker-common-candidate.
by centos-devel 30 Mar '16

Hi list! Apologies in advance for this has turned into a slightly long email, so I will put a short summary here at the top. I am not entirely sure if I am trying to do the right thing, so I thought it best if I were to explain clearly. TLDR: I think I need to install golang.x86_64 to make 'godeps go run' work. but yum fails with missing dependencies. Details follow. So I created a yum repo: cat << EOF > /etc/yum.repos.d/virt7-docker-common-candidate.repo [virt7-testing] name=virt7-testing baseurl=http://cbs.centos.org/repos/virt7-docker-common-candidate/x86_64/os/ gpgcheck=0 EOF I installed and configured docker-storage, docker, docker-registry. I then installed Kubernetes and managed to configure a test cluster with master and slave nodes running in VMs using CBS build from virt7-docker-common-candidate dated 10-Mar-2016 16:50 Having followed along ok with the Kubernetes 101 http://kubernetes.io/docs/user-guide/walkthrough/ and Kubernetes 201 http://kubernetes.io/docs/user-guide/walkthrough/k8s201/ I am attempting to follow along with the supplied examples. https://github.com/kubernetes/kubernetes/tree/release-1.2/examples I know very little about Go but If I am not mistaken, I need to install it to enable the k8s demos to build and function. particularly "Nginx https service" https://github.com/kubernetes/kubernetes/tree/release-1.2/examples/https-ng… The nginx-https example needs to build some certificates so a makefile calls 'godeps go run ...' error is: godep go run make_secret.go -crt /tmp/nginx.crt -key /tmp/nginx.key > /tmp/secret.json /bin/sh: godep: command not found make: *** [secret] Error 127 So I install [root@vm139 admin]# yum info godep.x86_64 Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirror.ox.ac.uk * extras: mirror.cov.ukservers.com * updates: repo.bigstepcloud.com Available Packages Name : godep Arch : x86_64 Version : 27 Release : 3.el7 Size : 1.8 M Repo : virt7-testing Summary : Dependency tool for go URL : https://github.com/tools/godep Licence : BSD Description : Dependency tool for go error is now: godep go run make_secret.go -crt /tmp/nginx.crt -key /tmp/nginx.key > /tmp/secret.json godep: No Godeps found (or in any parent directory) make: *** [secret] Error 1 ## My reading of that is that godep cannot run go because golang is not installed. ?

But am a bit stuck with getting go to function. So I attempt to install golang but this fails because of missing dependencies: Error: Package: golang-1.5.1-1.el7.x86_64 (virt7-testing) Requires: golang-src = 1.5.1-1.el7 Available: golang-src-1.4.2-1.el7.centos.noarch (extras) golang-src = 1.4.2-1.el7.centos Available: golang-src-1.4.2-9.el7.noarch (base) golang-src = 1.4.2-9.el7 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest Perhaps I am misunderstanding? Can anyone help me with this? Thanks Colin.
