The idea : Make all your Build with Jenkins on always the same environment : controlled, stable ..
What we will do :
- Jenkins run a docker container
- Jenkins run a temp slave in the container
- The build is done on the slave container and jenkins take the result of the build (logs, metadata, artifacts)
- Whent the build is done the container is killed
Pull a debian image
Prepare a dockerfile
FROM wheezy64:wheezy RUN apt-get install -y openssh-server openjdk-7-jre-headless RUN useradd -m -s /bin/bash jenkins RUN echo jenkins:jenkins | chpasswd RUN mkdir -p /var/run/sshd EXPOSE 22 CMD /usr/sbin/sshd -D
Build a jenkins image
docker build -t wheezy_jenkins:jenkins .
We can test by running the container and connect with ssh
$ jenkins=$(docker run -d -p 0.0.0.0:2222:22 -t -i wheezy_jenkins:jenkins)
$ ssh jenkins@localhost -p 2222
Whe exit from the ssh session
Then kill the container
docker kill $jenkins
Then delete the container
docker rm $jenkins
Now we will configure jenkins
install the docker plugin on jenkins (cf our post to know how to install plugin :jenkins_pluging )
configure jenkins : cloud and had your docker container
create an item
have to try this asap

Pull the JHipster Docker image:
sudo docker pull jdubois/jhipster-docker
Create a « jhipster » folder in your home directory:
Run The docker image, with the following options:
- The Docker « /jhipster » folder is shared to the local « ~/jhipster » folder
- Forward all ports exposed by docker (8080 for Tomcat, 3000 for BrowserSync from the « grunt serve » task, 3001 for the BrowserSync UI, and 22 for SSHD). In the following example we forward the container 22 port to the host 4022 port, to prevent some port conflicts:
sudo docker run -v ~/jhipster:/jhipster -p 8080:8080 -p 3000:3000 -p 3001:3001 -p 4022:22 -t jdubois/jhipster-docker
You can now connect to your docker container with SSH. You can connect as « root/jhipster » or as « jhipster/jhipster », and we recommand you use the « jhipster » user as some of the tool used are not meant to be run by the root user.
Start by adding your SSH public key to the Docker container:
cat ~/.ssh/id_rsa.pub | ssh -p 4022 jhipster@localhost 'mkdir ~/.ssh && cat >> ~/.ssh/authorized_keys'
You can now connect to the Docker container:
ssh -p 4022 jhipster@localhost
Your first project
You can then go to the /jhipster directory in your container, and start building your app inside Docker:
If the following exception occurs, you need to change the owner of the /jhipster directory. See next step.

You need to fix the jhipster folder to give the « jhipster » user ownership of the directory:
ssh -p 4022 jhipster@localhost
sudo chown jhipster /jhipster
Once your application is created, you can run all the normal grunt/bower/maven commands, for example:
Congratulations! You’ve launched your JHipster app inside Docker!
On your host machine, you should be able to :
- Access the running application at http://localhost:8080
- Get all the generated files inside your shared folder
As the generated files are in your shared folder, they will not be deleted if you stop your Docker container. However, if you don’t want Docker to keep downloading all the Maven and NPM dependencies every time you start the container, you should commit its state.
Generating SSH keys
Step 1 – Check for existing SSH keys.
ls -al ~/.ssh
# Lists the files in your .ssh directory, if they exist
Check the directory listing to see if you already have a public SSH key. By default, the filenames of the public keys are one of the following:
If you see an existing public and private key pair listed (for example id_rsa.pub and id_rsa) that you would like to use to connect to GitHub, you can skip Step 2 and go straight to Step 3.
Step 2 – Generate a new ssh key
ssh-keygen -t rsa -b 4096 -C "firstname.lastname@example.org"
it will ask you
Generating public/private rsa key pair.
Enter file in which to save the key (/home/jjz109/.ssh/id_rsa):
keep default and just press ENTER
you ‘ll have
Created directory '/xxxxx/.ssh'.
Enter passphrase (empty for no passphrase):
Choose a secure phrase
Your identification has been saved in /xxxxxx/.ssh/id_rsa.
Your public key has been saved in /xxxxx/.ssh/id_rsa.pub.
The key fingerprint is:
The key's randomart image is:
+--[ RSA 4096]----+
| xxxxxx |
| xxxxxxxx |
|xx xxx xx |
| * * xx |
|. xxxx |
|. xxx |
Step 3 – Add this key to the agent
Be sure ssh agent is running in background
$ eval "$(ssh-agent -s)"
It will give you the PID
Add your SSH key to the ssh-agent:
$ ssh-add ~/.ssh/id_rsa
The result should be :
identity added xxxxxxxxxxxx
Step 4 – Add the SSH key to your account
install xclip with apt-get :
sudo apt-get install xclip
xclip -sel clip < ~/.ssh/id_rsa.pub
this will copy your key to the clipboard
Connect to your github account and go in SETTING
select SSH Key
Choose Add key
Past the key you have in your clipboard
Step 5 – Test the connection
ssh -T email@example.com
This will ask you the passphrase after you said yes to the first question
If the username in the message is yours, you’ve successfully set up your SSH key!
1 – Install Git
sudo apt-get install git
2 – Create a github account on GITHUB
3 – configure your git on your linux
git config --global user.name "user_name" where user_name is your github login
git config --global user.email "email" where email is your email used on github
Before the next step I will propose you to see our post about using SSH beetwin git and github
Here is the post :GIT GITHUB and SSH
4 – Create a local repository
Create a folder in your system. This will serve as a local repository which will later be pushed onto the GitHub website.
Use the following command:
git init devops_pm_rep
On github you can try to fork an existing project , for example
Connected you can clic on the fork button to add this project to your account
When your github account is ok , you can create a local clone on your computer by using git
On github, on the right you’ll find a https clone url field. Copy the link.
something like : https://github.com/xxxxxxxx/jhipster_example.git
in a terminal:
git clone https://github.com/xxxxxxxx/jhipster_example.git where xxxxis your user-name
It should do:
Clonage dans 'jhipster_example'...
remote: Counting objects: 6, done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 6 (delta 0), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (6/6), done.
Vérification de la connectivité... fait.
You can now ask git to sync your clone with the original repository (orignal is not your fork but the project you forked)
copy the url to the original project. in the example :
in your terminal : go to the repository where you put your git clone
when you find your .git
git remote -v will show your repositories
git remote add upstream https://github.com/jjz109/jhipster_example.git
wil add this upstream
Now, you can keep your fork synced with the upstream repository with a few Git commands
Sync a fork of a repository to keep it up-to-date with the upstream repository
git fetch upstream
# remote: Counting objects: 75, done.
# remote: Compressing objects: 100% (53/53), done.
# remote: Total 62 (delta 27), reused 44 (delta 9)
# Unpacking objects: 100% (62/62), done.
# From https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY
# * [new branch] master -> upstream/master
Fetch the branches and their respective commits from the upstream repository. Commits to master will be stored in a local branch, upstream/master
Check out your fork’s local master branch
$ git checkout master
# Switched to branch 'master'
Merge the changes from upstream/master into your local master branch. This brings your fork’s master branch into sync with the upstream repository, without losing your local changes.
$ git merge upstream/master
Syncing your fork only updates your local copy of the repository. To update your fork on GitHub, you must push your changes.
Pushing to a remote
git push to push your local branch to a remote repository.
The git push command takes two arguments:
A remote name, for example,
A branch name, for example,
As an example, you usually run git push origin master to push your local changes to your online repository.
