Cannot git-clone an OpenShift application

Question

I just opened an OpenShift account, and went through this tutorial:

https://www.openshift.com/blogs/any-version-of-nodejs-you-want-in-the-cloud-openshift-does-it-paas-style

When I got to creating the app, I got the following error:

erelsgl@erelsgl-H61MLC:~/mynode$ sudo rhc create-app mynode nodejs-0.6

Answer 1

I got exactly the same issue and found the solution, under windows. It seems you are under Linux, but may be this will give you ideas.

First you need to make sure your SSL keys have been created properly for Git (check this post on my blog for instructions).

Then, using Git for Windows, right click on the folder to clone the project and enter the SSL URL:

Make sure you check Load Putty Key and select the path to your .ppk file. This worked like a charm for me.

May be you need to specify the path to your private key file under Linux when cloning from the command line.

Protozoal

Strange thing, I do not want to install another program (here Tortoise) on windows.It should work on the cmd, git should find the .ssh folder and should look up automatically the ppk or private key or whatever. – Boiler

again me.In the webconsole my key name is "tommueller" and not "default". Could this be an issue? BTW, the ppk file used while git makes sense because you need a ppk while "ssh"ing (ssh works for me) – Boiler

I tried to use the git clone cmd when right clicking the folder for tortoise git. But there is no git clone , but many others. Furthermore, does tortoise also provide the "load putty key" when I commit? – Boiler

Answer 2

Your mistake is you are clone the repository inside app's host, this goes to clone your repository inside your application host on openshift, then it gives you a permission denied to write access on host, you must close it in your local.

First Open a Command Prompt, then type:

mkdir apprepo
cd /d apprepo
git clone ssh://[email protected]/~/git/mynode.git/

and if you have any changes in repository:

git commit -a
git push

Answer 3

It looks like you are having issues with your ssh key. Have you added one to openshift? You can run rhc sshkey list to check. Make sure that one of these private keys is in your ssh folder, C:\user\\[username]\\.ssh\ for windows and ~/.ssh on linux (Note that on both os's they are hidden folders). Openshift refuses to let you do anything with the git repo unless it can verify your ssh key. Take a look at this Openshift SSH Documentation for more details.

Cressy

I have a single ssh key (see the edit to my question). How can I check if it is in my ssh folder? My ssh folder (on Linux) contains 3 files: id_rsa, id_rsa.pub, and known_hosts. Non of them contains a fingerprint.. – Presidio

try rhc sshkey add. If you still are getting errors after trying this, open up your id_rsa.pub file and copy it. Paste it into the public key section of openshift.redhat.com/app/console/keys/new to add your current public ssh key into openshift. – Cressy

I opened the console, and found out that my public key is already there (under the name "default")... probably there is some other problem. – Presidio

I still think it is ssh problem. The fact that the server denied your git push means that something ssh related is not lining up. Here is a openshift documentation page for your permission denied error that I found. openshift.com/kb/… – Cressy

Answer 4

go to preference in eclipse and in ssh key menu, click KEY MANAGEMENT and ther is a rsa key tab click that and copy your public key and click the button save as private key... then go to your open shift application and paste your public key and work on it... i hope it working

Answer 5

Don't use sudo when creating your app or when using rhc

Curley

try creating the app inside a folder where you have write permissions. The rhc command will attempt to create a local git repository for you to work with. You can disable this behavior by using the --no-git flag. – Germiston

Answer 6

This seems to be the thread for answering SSH key related issues, even if the answer relating to not cloning on the host machine seems to make the most sense.

Regarding the configured keys being good for opening an SSH connection but not for git cloning, I tried everything in this thread and on the OpenShift site and eventually discovered that Git for Windows wasn't using the SSH keys managed by Pageant; the only way for me to clone my repository was to have the Git GUI generate a new key for me and then add that one's public key to my OpenShift application as well.

I'm posting this answer here because I don't know where else I should, I hope it's helpful!

Answer 7

I have the same problem as you, and got an idea based on ʀɣαɳĵ answer

Don't use sudo when creating your app or when using rhc

Considering this recommendation I tried deleting my app and re-creating it using my user without using sudo, but I received some permission errors indicating problems accessing:
- .openshift folder under my user home folder
- .ssh/rsa* documents under my user home folder also
- My actual directory where a new directory would be created as part of the app creation

After granting access to those resources using chmod:
- chmod 755 for both .openshift and .ssh/rsa*
- chmod -R 777 mydir in my actual directory

I re created the app (rhc create app yourAppName platform ) and everything is working fine now!

Hope it helps you.
