I am creating image using packer. I have used 2 provisioners i.e Shell and ansible-local and both are working fine and installed all the required packages.
But now i need to deploy my application code too into my image which is over Gitlab.
I am out of idea how we can do this. Can you please help me how we can fetch the code from Gitlab to create image using packer?
Any assistance will be appreciated.
Thanks.
You should use ssh agent forwarding.
On the host running Packer load a ssh key that have access to git repository ssh-add <path to private key>.
Ensure that you have "ssh_disable_agent_forwarding": false (default) in your packer template. See Docs: Communicator.
Now in your packer provisioning script you should be able to clone the repository over SSH with git clone git#<GitLab server>:<repo.git>.

How can I create and use the imagestream of jboss webserver in openshift origin ?
Image yaml available in this link. I see that it is automatically built with openshift enterprise version (link) . but why not in origin ?
Thanks.
I expected it to pull itself the image during build but did not happen.
D:\docker\apps>oc new-build --image-stream=jboss-webserver31-tomcat7-openshift:1.1 --name=newapp --binary=true
warning: Cannot find git. Ensure that it is installed and in your path. Git is required to work with git repositories.
error: unable to locate any images in image streams with name "jboss-webserver31-tomcat7-openshift:1.1"
The 'oc new-build' command will match arguments to the following types:
1. Images tagged into image streams in the current project or the 'openshift' project
- if you don't specify a tag, we'll add ':latest'
2. Images in the Docker Hub, on remote registries, or on the local Docker engine
3. Git repository URLs or local paths that point to Git repositories
--allow-missing-images can be used to force the use of an image that was not matched
See 'oc new-build -h' for examples.
So I tried to create the import yaml in webconsole but got below error with yaml.
Failed to process the resource.
Resource is missing kind field.
Got it. Apparently one has to be logged in redhat
oc import-image my-jboss-webserver-3/webserver31-tomcat7-openshift --from=registry.access.redhat.com/jboss-webserver-3/webserver31-tomcat7-openshift --confirm
I have make a job in jenkins in local and all work except sending an email at the end (but that is normal when I work in local). Now I need to migrate this job in my jenkins server.
During the build, I use a json file in the script shell "newman run ../../workflow-libs/testCollections" and I don't know how to use this (testCollection) file in my jenkins server.
Any help would be appreciated.
You said you are using shell scripting. So you can simply cd <Path Here> to change your directory. And in your case,
cd $WORKSPACE
newman run ../../workflow-libs/testCollections
You can simply do this. If you don't know how to create that file in jenkins server, Please login using jenkins cli and move or copy the file from local. Hope this helps.
I try to learn about Open Shift, how it works, how to run apps, build images etc.
To start with something, which I thought will be rather simple, I decided to run a pod with pure centos7 OS, based on this image. I installed locally minishift v1.11.0+4459917, I created a new project, and performed command:
oc new-app openshift/base-centos7 in this project. As a result I received the following message:
--> Found Docker image bb81a09 (11 months old) from Docker Hub for "openshift/base-centos7"
* An image stream will be created as "pon3:latest" that will track this image
* This image will be deployed in deployment config "pon3"
* The image does not expose any ports - if you want to load balance or send traffic to this component
you will need to create a service with 'expose dc/pon3 --port=[port]' later
* WARNING: Image "openshift/base-centos7" runs as the 'root' user which may not be permitted by your cluster administrator
--> Creating resources ...
imagestream "pon3" created
deploymentconfig "pon3" created
--> Success
Run 'oc status' to view your app.
As I can see in the warning this image runs as root, which is clearly not a good practice, but it may be worked around, as described here and here. I tried both approaches - I have created a new service account with anyuid scc, and I assigned anyuid scc to default sa. Unfortunately I'm still not able to run a pod based on this image. The result looks like this:
oc get pods
mycentos-1-deploy 1/1 Running 0 32s
mycentos-1-p1vh5 0/1 CrashLoopBackOff 1 30s
I try to troubleshoot this way:
oc logs -p mycentos-1-p1vh5
This image serves as the base image for all OpenShift v3 S2I builder images.
It provides all essential libraries and development tools needed to
successfully build and run an application.
To use this image as a base image, you need to have 's2i/bin' directory in the
same directory as your S2I image Dockerfile. This directory should contain S2I
scripts.
This base image also provides the default user you should use to run your
application. Your Dockerfile should include this instruction after you finish
installing software:
USER default
The default directory for installing your application sources is
'/opt/app-root/src' and the WORKDIR and HOME for the 'default' user is set
to this directory as well. In your S2I scripts, you don't have to use absolute
path, but rather rely on the relative path.
To learn more about S2I visit: https://github.com/openshift/source-to-image
Additionally I tried to troubleshoot with oc adm diagnostics but to be honest I didn't see anything relevant to this issue.
I'm clearly missing something here. Can someone give me a hint how this should be handled or how can I try to troubleshoot this? Is there a different way to run pure centos OS?
Thank you for any help.
You need the image you want to deploy using oc new-app to have an actual application in it. The openshift/base-centos7 image is a base image only on which other images are built and doesn't have an application in it.
If you just want to spin up a container and be presented with a shell environment in which you can play in use the oc run command instead.
OpenShift isn't like a traditional VPS where you just spin up permanent shell environments which you then access to set up your application manually. The idea is that you build your application into an image and deploy the application.
I would suggest you go read:
https://www.openshift.com/promotions/for-developers.html
https://www.openshift.com/promotions/devops-with-openshift.html
and work through the exercises at:
https://learn.openshift.com
to learn more about what OpenShift is and how to use it.
I am trying to clone to my local git repository.
From Mac terminal:
git clone git_url directory_to_create
In the web console, I tried to use the GitHub Webhook URL and Generic Webhook URL. But I got this error: The requested URL returned error: 405
Any suggestions?
OpenShift doesn't host a Git repository for you. It relies on you having a separate hosted Git repository to pull application source code from. Alternatively, you can use a binary input build and push source code from your local system.
If you already have a deployed application how did you create it?
If it was a sample S2I application, you need to go to GitHub where the source code for that sample application was and clone it into your GitHub account. You can then check it out from your fork in your own GitHub account to your local system. You will though need to update the build configuration for the application in OpenShift to then use your fork of the original sample application.
How to perform automatic cloning of github repository and that repository should be copied in one folder automatically using node js..??
I have used this link http://www.nodegit.org/ and followed all the steps to clone the repository which are given here..but still getting these two error.
%1 is not a valid windows 32 application and Failed to load resource: the server responded with a status of 500 internal Servor error.
Any help will greatly be appreciated..??
I create a ruby library that allow anyone to clone multiple Github repository easily in one simple command using your own credential.
If you have ruby install then you could run something like
$gem install github-cloner
$github-cloner --user awesome_user
--base-dir ~/Desktop/github
--languages "JavaScript"
--clone
Detail installation and sample usage are in the README.md of the project.
