Puppet required?
by Avram Lubkin 06 May '13

06 May '13

I was looking over the project and it looks interesting, much improved over Spacewalk. I particularly like how different projects are used instead of one monolithic project. There's just one thing that concerns me. It looks like if I want to do provisioning I have to use Foreman and if I use Foreman I have to use Puppet. Since Puppet requires ruby installed on all clients I can't deploy it. This is due to a security requirement. I can't add interpreters to a system unless I have a good justification. I can do what puppet does without adding another interpreter, so I can't justify it. I know there are lots of organizations that use puppet and probably install Ruby to support it, but I've never worked with a group that would allow that. Any plans to support CFengine or something similar that wouldn't require another interpreter on the clients? Python is Okay too, since any RHEL or RHEL-like system already has it. Please reply all, not on the list. Thanks, Avram

Katello postgres backends - replication and failover via pgpool-II
by corey welton 25 May '12

25 May '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 All, Below is a wiki article I've written that outlines a little preliminary research I've done on using pgpool-II as a layer between katello and the postgres backend, in order to enable db replication and failover. https://fedorahosted.org/katello/wiki/KatelloFailoverUsingPGPoolII A few [very considerable] caveats: * It's not currently possible to install katello natively against pgpool[1]. It could probably be done with some tweaks to katello-configure and/or katello/candlepin config files, but I haven't figured those changes out. Right now ,initially, you'll have to: (a) install it, (b) shut it (and all associated services) down, (c) manually copy a snapshot of katelloschema/candlepin over to your other dbs, and (d) point katello and candlepin to your pgpool-II port (9999) vs postgres (5432), before restarting. * The scope of this experiment is limited to the postgresql portions of katello -- katello itself and candlepin. Pulp, which uses mongodb, is not covered here. * There has not been a great deal of research done on this beyond creating users, orgs, etc. This was a proof-of-concept effort. What does this mean? * Here there be dragons! !!!This is not a supported configuration!!! * There's a lot of curious things for those interested in trying out new stuff! A few higher-priority tasks to look into might be: 1. Figuring out necessary modifications to katello-configure, etc., to be able to natively install against pgpool 2. Work out the bugs seen when using pgpool's query_cache, particularly figuring out why Organizational environments don't seem to display with it enabled. 3. Figuring out how to enable and automate db node recovery - when a node goes down, how does it get brought back up to par (Slony? WAL?) 4. Once #3 is figured out, assure that the failover actually functions. It _should_ "just work" but I've only go so far as to test replication since I haven't figured out #3. Lower priority tasks might be: 1. Experiment with parallel queries (a feature supported by pgpool). 2. Affinity configurations/multi-headed pgpool instances 3. Experiment with load-balancing (a feature supported by pgpool). Actually, I have been running with this enabled but haven't done any real tests. Anyway, I'd be interested in seeing what sort of things anyone else could figure out. I'm not a pgsql expert so I am kind of reaching the outer limits of my current knowledge on that front. Anyone? Anyone? Bueller? Thanks, Corey.

New katello build available
by Lukas Zapletal 24 May '12

24 May '12

Hello, we prepared new build today. There is still liquibase workaround needed. (*) The liquibase update is now in process of getting into the stable (Fedora and EPEL), its just a matter of few days to get there. The version must be higher than -7 so be sure to use the workaround (*) or wait until weekend. Also with Fedora 16+ you can run into issues with mongodb initialization. This is because mongodb preallocates about 3 GBs of data during its first start and puppet can fail configuring Pulp because socket is not ready during initialization. On Fedora please start mongo BEFORE katello-configure and wait about 3 minutes until it responds (you can use "mongo" command to connect to the database). We will deliver fix next week. (*) Workaround: #!/bin/bash FEDORA_VERSION=$(rpm -q --queryformat '%{VERSION}' fedora-release) echo Fedora version: $FEDORA_VERSION REDHAT_VERSION=$(rpm -q --queryformat '%{VERSION}' redhat-release-server) echo Red Hat version: $REDHAT_VERSION CENTOS_VERSION=$(rpm -q --queryformat '%{VERSION}' centos-release) echo CentOS version: $CENTOS_VERSION if [ "$FEDORA_VERSION" == "16" ]; then cat > /etc/yum.repos.d/goodwin.repo <<EOF # temporary until its there [epel-goodwin] name=Extra Goodwin Packages for F16 - \$basearch baseurl=http://repos.fedorapeople.org/repos/dgoodwin/liquibase/fedora-16/x8… enabled=1 gpgcheck=0 EOF fi if [ "$REDHAT_VERSION" == "6Server" -o "$CENTOS_VERSION" == "6" ]; then cat > /etc/yum.repos.d/goodwin.repo <<EOF # temporary until its there [epel-goodwin] name=Extra Goodwin Packages for Enterprise Linux 6 - \$basearch baseurl=http://repos.fedorapeople.org/repos/dgoodwin/liquibase/epel-6/x86_6… enabled=1 gpgcheck=0 EOF fi yum -y install liquibase postgresql-jdbc -- Later, Lukas "lzap" Zapletal #katello #systemengine

Katello in Fedora 16
by Pavel Pokorný 21 May '12

21 May '12

Hi, I am trying to install Katello on clean Fedora 16 in VirtualBox. After few hours its still not working. I find out from logs that liquibase and tcnative packages were missing and required. Then I had to change ownership of some folders (mentioned in comment of bug report). But there is still some problem with ssl certificates I think. Could somebody help me with this? $ sudo katello-configure Starting Katello configuration The top-level log file is [/var/log/katello/katello-configure-20120518-231646/main.log] err: /Stage[main]/Candlepin::Service/Exec[wait for candlepin]/returns: change from notrun to 0 failed: Command exceeded timeout at /usr/share/katello/install/puppet/modules/candlepin/manifests/service.pp:10 katello-debug https://www.dropbox.com/s/2r1tj2yl07tp9h1/katello-debug-20120518232351.tar.… $ sudo /usr/share/candlepin/cpsetup candlepin.conf already exists, skipping...

I somehow managed to get over this error first time but I cant remember how. But after this there was another error - candlepin on port 8443 was not available. What have I done wrong? I tried to follow https://fedorahosted.org/katello/wiki/Install.

New stable build - workaround needed
by Lukas Zapletal 21 May '12

21 May '12

Hey all, we have a new stable build in the repo. katello-0.2.38-1.fc16.noarch katello-cli-0.2.36-1.fc16.noarch katello-agent-1.0.3-1.fc16.noarch pulp-1.1.8-1.fc16.noarch candlepin-0.6.2-1.fc16.noarch There is still an issue with a liquibase dependency, that can lead to cpsetup errors. Please note you need liquibase-2.0.3-7, there is already an older version (liquibase-2.0.3-6) in Fedora 16 which does NOT work correctly. Having said that, you still need manually install liquibase because of missing require in candlepin. As a workaround, you need to add Devan Goodwin's repository and install liquibase manually before you proceed with katello-configure. This script should do the work for you: #!/bin/bash FEDORA_VERSION=$(rpm -q --queryformat '%{VERSION}' fedora-release) echo Fedora version: $FEDORA_VERSION REDHAT_VERSION=$(rpm -q --queryformat '%{VERSION}' redhat-release-server) echo Red Hat version: $REDHAT_VERSION CENTOS_VERSION=$(rpm -q --queryformat '%{VERSION}' centos-release) echo CentOS version: $CENTOS_VERSION if [ "$FEDORA_VERSION" == "16" ]; then cat > /etc/yum.repos.d/goodwin.repo <<EOF # temporary until its there [epel-goodwin] name=Extra Goodwin Packages for F16 - \$basearch baseurl=http://repos.fedorapeople.org/repos/dgoodwin/liquibase/fedora-16/x8… enabled=1 gpgcheck=0 EOF fi if [ "$REDHAT_VERSION" == "6Server" -o "$CENTOS_VERSION" == "6" ]; then cat > /etc/yum.repos.d/goodwin.repo <<EOF # temporary until its there [epel-goodwin] name=Extra Goodwin Packages for Enterprise Linux 6 - \$basearch baseurl=http://repos.fedorapeople.org/repos/dgoodwin/liquibase/epel-6/x86_6… enabled=1 gpgcheck=0 EOF fi yum -y install liquibase katello-configure ...

Katello on CentOS
by Lukas Zapletal 16 May '12

16 May '12

Hello, today I successfully installed on CentOS and it's looking good. I added just one line on our installation wiki page: https://fedorahosted.org/katello/wiki/Install It's because of katello-agent (requires rhsm which is not in CentOS). Happy hacking. -- Later, Lukas "lzap" Zapletal #katello #systemengine
