I have an application in Openshift free plan with only one gear. I want to change it to scalabe and take usage of all of 3 free gears.
I read this blog post from openshift and I found that there is a way to do it. I should clone my current application to a new one as a scalable which will use the 2 remaining gears and then I will delete the original application. Thus, the new one will have 3 free gears.
The way that blog suggest is: rhc create-app <clone> --from-app <existing> --scaling
I have the following error: invalid option --from-app
Update
After running the command gem update rhc, I don't have the error above but...A new application with the given name has created with the same starting package (Python 2.7) just like the existing one, but all the files are missing. It actually create a blank application and not a clone of the existing.
Update 2
Here is the structure of the folder:
-.git
-.openshift
-wsgi
---static
---views
---application
---main.py
-requirements.txt
-setup.py
From what we've talked on IRC, your problem was around missing SSH configuration on Windows machine:
Creating application xxx ... done
Waiting for your DNS name to be available ...done
Setting deployment configuration ... done
No system SSH available. Please use the --ssh option to specify the path to your SSH executable, or install SSH.
I've double checked it, and it appears to be working without any problem.
The only requirement is to have the latest rhc client and putty or any other
SSH client. I'd recommend going through this tutorial once again and double-check everything to make sure everything is working properly.
Make sure you are using the newest version of the rhc gem with "gem update rhc" to make sure that you have access to that feature from the command line.
The --from-app will essentially do a 'rhc snapshot save & snapshot restore` (amoung other things) as you can see here from the source:
if from_app
say "Setting deployment configuration ... "
rest_app.configure({:auto_deploy => from_app.auto_deploy, :keep_deployments => from_app.keep_deployments , :deployment_branch => from_app.deployment_branch, :deployment_type => from_app.deployment_type})
success 'done'
snapshot_filename = temporary_snapshot_filename(from_app.name)
save_snapshot(from_app, snapshot_filename)
restore_snapshot(rest_app, snapshot_filename)
File.delete(snapshot_filename) if File.exist?(snapshot_filename)
paragraph { warn "The application '#{from_app.name}' has aliases set which were not copied. Please configure the aliases of your new application manually." } unless from_app.aliases.empty?
end
However this will not copy over anything in your $OPENSHIFT_DATA_DIR directory so if you're storing files there, you'll need to copy them over manually.

I'm using apparmor as hardening layer for libvirt-qemu , everything is OK , but there is one thing that I can't solve systematically, let me explain :
When create a new qemu instance , profile is generated from /etc/apparmor.d/libvirt/TEMPLATE.qemu to a file with path /etc/apparmor.d/libvirt/libvirt-81303229-df4c-4b18-b33b-277bcda81b0f for example .
When instance is shut-off profile is unloaded from kernel by apparmor and it is OK as expected. But if i remove the instance definitively, i would expect that profile is removed also from filesystem, but it is not and still present in filesystem. After some time I have very big mess in libvirt instance profile files
Yes .. I can write a cron job what will be delete unnecessary libvirt profile files ... but ..is there some more clear solution , maybe builtin function of apparmor ?
Thanks
Are you using libvirt undefine to delete the stopped guest? It appears that virt-aa-helper should delete an undefined domain but I think it is a bug and you should file a ticket.
You can use the virt-aa-helper command directly to remove the files which is probably the safest as it should deal with the dependencies for you.
An example command is:
$ sudo /usr/lib/libvirt/virt-aa-helper -D -u libvirt-3c3d5aa2-f581-457d-b5ab-efbf9fdd4a6e
But it may be some edge case that they need to account for, where you can undefine a running instance to convert it to ephemeral. You would need to take care of that edge case.
Note: Because virt-aa-helper is intended to be run by libvirt you will have to use sudo with the command. If you do not it will silently fail and not remove the profile.
My objective: get https://github.com/couchbaselabs/ToDoLite-iOS syncing with a Couchbase Server and sync gateway on localhost rather than the default demo URL.
I run sync gateway like so: bin/sync_gateway -url http://localhost:8091
And then the only thing I changed in the example is:
-#define kSyncGatewayUrl #"http://demo.mobile.couchbase.com/todolite"
+#define kSyncGatewayUrl #"http://localhost:4984/sync_gateway/"
And when I run
Error: Error Domain=CBLHTTP Code=404 "404 not_found" UserInfo=0x7ff11941fb50 {NSURL=http://localhost:4984/sync_gateway/_facebook, NSLocalizedFailureReason=not_found, NSLocalizedDescription=404 not_found}
How do I fix this?
I solved it. The reason is that I ran sync_gateway without enabling Facebook registration support.
Normally this is done in config.json file. In fact, this configuration file was supplied in ToDoLite all along.
It is crucial that you launch sync_gateway with this configuration file. The README actually states this but in a loose and casual way...
cd ToDoLite-iOS
sync_gateway -url http://localhost:8091 sync-gateway-config.json
NB: I assume above that sync_gateway has been made accessible through $PATH. It's a good idea to do that anyway.
Also, I didn't pay attention to the dbname. So you'll need to replace
#define kSyncGatewayUrl #"http://demo.mobile.couchbase.com/todolite"`
with
#define kSyncGatewayUrl #"http://localhost:4984/todos"
So, what's the complete sequence of steps to get it working?:
If you want to wipe everything on the server, rm -rf Library/Application\ Support/Couchbase and start over. Homebrew cask hides this setting somewhere else where it's hard to reset so a manual install is very recommended.
Install Couchbase Server
Set up login credentials if fresh install; otherwise just login
Create a bucket (a database) with name todos on the cluster. This is the dbname used by TODOLite.
Launch sync gateway. Be sure to pass in the replication URL AND the JSON config file.
bin/sync_gateway -url http://localhost:8091 sync-gateway-config.json; keep sync gateway running
In the TODOLite AppDelegate.m, change kSyncGatewayUrl:
#define kSyncGatewayUrl #"http://localhost:4984/todos". Notice the name of the database is necessary!
(Optionally) Access the administrator interface of the sync gateway by going to http://localhost:4985/_admin/db/sync_gateway/sync. You can set up the sync function here.
In case you're wondering where those port numbers came from, check out
ports Couchbase Server uses
ports Sync Gateway uses
4984 — SG API port
4985 — SG admin server
The default remote sync URL will be defined in different files depending on the version of the project you download (iOS, Android, PhoneGap, and Motion). To find the appropriate string to change simply search through your project for the URL "http://demo.mobile.couchbase.com/todolite" and replace it with the URL of your new sync gateway database.
I'm trying to save an App snapshot on OpenShift, however it complains that my application isn't found. When I type rhc apps my application is correctly listed, not sure what I could be doing wrong.
For example:
appname # http://appname-domain.rhcloud.com
when I run rhc snapshot save -a appname, I get:
Application 'appname' not found.
If the application is not in your default namespace, then you will need to add the -n option to your rhc snapshot save command. That could be your issue.
we've updated hudson to jenkins and have a few dependencies upon the "hudson" user we used to have.
Now that we have jenkins running (works fine) we'd like it to run as the user "hudson" in order to keep our other processes intact without having to rewrite them.
We found instructions on how to do this BEFORE installing jenkins, but we're already past that point. Jenkins is installed and up and running. Is there a way to let jenkins run as the user "hudson"?
We are running CENTOS
Jenkins usually runs with it's own user, so there are two main issues to handle:
Make sure user 'hudson' has full access to the files of user 'jenkins' (or whatever user it was set to run as).
Start the Jenkins-daemon (or other initiator) with the 'hudson' user.
(another approach is to change the user-ID so it is actually the same user but with two names)
Good luck!
If you've installed Jenkins from RPM, there should be an /etc/sysconfig/jenkins file with a JENKINS_USER setting that defaults to 'jenkins' that you can change to 'hudson'.
I second Gonen's comment above about making sure you change the ownership of the 'jenkins' owned files to 'hudson'. Don't forget about the /var/log/jenkins logs.
Also don't forget to restart the Jenkins service after updating the files.
After installing and playing around with mercurial , I am trying to get Hudson to clone the repository so it can build my project.
At the moment the following task works.
I Can sync to my external host and the code shows up on that host.
Now I am trying to configure hudson / jenkins to access the code on my host.
But unfortunately I am rolling on a error:

What actions do i need to do to tell Hudson to use username x and password y to acces the data?
Edited => Found how to integrate ssh .
Used SSH instead of https
Download putty.exe, puttygen.exe, pageant.exe, and plink.exe from the PuTTY website.
Start puttygen and generate a key in OPENSSH FORMAT (hudsons format) (=> How to use Svn + SSH )
Click the Save private key button and save the .PPK file somewhere.
Click the Save public key button and save it.
Go to your website and enter the public ssh-key
Run pageant.exe. The pageant icon (a computer wearing a hat) will show up in the status tray.
Right-click the pageant icon and choose Add Key.
Choose the .PPK file you saved earlier and type in its passphrase.

Install the Mercurial plugin in Hudson
All that’s left to do now is install
the Mercurial plugin in hudson. In a
browser, go to
http://INSERT_YOUR_IP_HERE:8080.
Hudson should come up.
Click on “Manage Hudson” and go to
“Manage Plugins”. Go to the
“Available” tab, check “Hudson
Mercurial plugin” and hit the
“Install” button. Hudson will prompt
you to restart, and then it’s
installed.
After that, just create a new job and
you’ll have a new “mercurial” option
in the “source control management”
section. Select that and put the ssh
URL in the “Repository URL” field.
Then put “default” in the “branch”
field and set up the rest of the job
to build/test your code (an exercise
left to the reader).
and here it is the first succesfull build !
Conclusion : This is a summary of all the small blogpost scattered arround the internet. I hope this post helps you in starting hudson and mercurial.
I think the problem is not related to username and password. Your stacktrace tells you there's something wrong with the path F:\Hudson\jobs\testproject\workspace.
Cannot run program hg (in directory
"F:\Hudson\jobs\testproject\workspace")
The directory name is invalid
Anyway, you can specify the username and password in the URL like: http://user:password#mydomain.org.
To authenticate the Jenkins/Hudson Mercurial plugin with BitBucket I too found it useful to use the SSH protocol instead of HTTPS particularly since:
there doesn't seem to be a way to store your HTTPS credentials to BitBucket with the Mercurial Jenkins plugin, but with SSH you can safely and securely store your credentials
with SSH you can configure it to use compression, which Mercurial doesn't do natively.
Good instructions for setting up SSH access to BitBucket are available here: http://confluence.atlassian.com/display/BITBUCKET/Using+SSH+to+Access+your+Bitbucket+Repository
Notes:
If you are running Jenkins/Hudson on a *nix server, you will want to login as the user running the Jenkins process and perform these operations from that users home directory, so the configurations will be found by that user (e.g. on my Debian server installation of Jenkins standalone, the user 'jenkins' is created and the home directory is set to '/var/lib/jenkins' [not /home/jenkins] - where I performed the instructions provided at the above link).
I found it very helpful to assure the hg clone command worked from the command line before attempting to have Jenkins call it.
IMPORTANT: In order to get this to work, I had to generate a key ** without ** a passphrase.
You can add the following lines to jenkins .hgrc file (usually /var/lib/jenkins/.hgrc)
[auth]
bitbucket.prefix = https://bitbucket.org/your_user/...
bitbucket.username = your_user
bitbucket.password = ******
See http://www.selenic.com/mercurial/hgrc.5.html#auth
You can add your scm credentials in the 'Credentials` section of Jenkins:
Also change the job configuration to use the credentials:
