We're currently evaluating CI servers and Travis CI caught our eye since it is a hosted solution. I haven't been able to find any information about it being able to deploy to Scalr though. Has anyone had any luck setting this up? I found information about using Jenkins to deploy to Scalr but I'd rather not go with Jenkins.
Thanks.
Deploying an application upon a Travis CI build success if functionally similar to deploying one upon a Jenkins success. All you need to do is to hook in to Scalr through its API when you build succeeds.
Using Travis CI, you can't really run arbitrary post-build shell scripts (unlike Jenkins). This makes integration a bit more complicated than using Jenkins (with Jenkins you just use the Scalr Command Line Tools to call the Scalr API), but it remains feasible.
All you need to do is have Travis CI send a notification to a Webhook Endpoint to a webapp you control (host that on your cloud infrastructure, or on e.g. Heroku), and have that webapp call the Scalr API.
Disclaimer: I work at Scalr.

I'm little confused about Jenkins and was hoping someone could clarify some matter for me.
After reading up on Jenkins, both from official docs and various tutorials I get this:
If I wanna set up auto deplyoment or anything Jenkins related, I could just install docker jenkins image, launch it and access it via localhost. That is clear to me.
Then, I just put Jenkinsfile into my repository, so that it knows what and how to build my repo and stuff.
The questions that I have are:
It seems to me that Jenkins needs to be running all the time, so that it can watch for all the repo changes and trigger code building, testing and deploying. If that is the case, I'd have to install Jenkins on my droplet server. But how do I then access my dashboard, if all I have is ssh access?
If Jenkins doesn't need to be up and running 24/7, then how does it watch for any changes?
I'll try to deploy my backend and front apps on docker-compose file on my server. I'm not sure where does Jenkins integrates in all that.
How Jenkins can watch for all the repository changes and trigger code building, testing and deploying?
If Jenkins doesn't need to be up and running 24/7, then how does it watch for any changes?
Jenkins and other automation servers offer two options to watch source code changes:
Poll SCM: Download and compare source code at predefined intervals.This is simple but, hardware consumption is elevated and is a little outdated
Webhooks: Optimal functionality offered by github, bitbucket, gitlab, etc. in which Github, for example, at any git event, makes an http request to your automation server, sending all the information like branch name, commit author, etc). Here more info about webhooks and jenkins.
If you don't want a 24/7 dedicated server, you can use:
Some serverless platform or just a simple application able to receive http posts + webhook strategy. For instance, Github will perform a post requet to your app/servlerless and at this point, just execute your build, test or any other commands to deploy your application.
https://buddy.works/. It is like a mini-jenkins.
If I'd have to install Jenkins on my droplet server. But how do I then access my dashboard, if all I have is ssh access?
Yes. Jenkins is an automation server, so it needs its own dedicated server.
You can install jenkins manually or use docker in your droplet. Configure 8080 port for your jenkins. If everyting is ok, just access to your droplet public ip offered by digitalocean, like: http://197.154.458.456:8080. This url must load the Jenkins dashboard.
from the last week i am working with jenkins, and its going good but at the end of R&D I have lost of confusion, these are questions which confusingto me.
How to do Continuous Integration with jenkins of Website?
hoe to view Testing analysis reports produced by sonarqube server to my local system?
what happens where all my developers will do commit and push at the same time on repository?
How to deploy my web application on targeted server using jenkins?
How to I use sonarqube to test my website ?
If you are building a .net website, install msbuild plugin in jenkins. Create a jenkins job, add a step checkout your website (git/svn - install required repo plugin). Schedule to run nightly or hourly depending on your needs.
Type in url for your sonarqube server and then you can view the reports.
This is not an issue if your developers are comitting simultaneously. Usually a CI tool such as Jenkins will take care of that.
This is called continuous deployment or continuous delivery. Something like Octopus Deploy can help you if you are deploying .net applications. You can use the tool octo.exe and pass the API key as parameter to deploy to a specific environment.
SonarQube is used as a quality gate for code analysis. It is not a test framework. Try to investigate on how to use selenium framework for automation testing.
I hope that I have answered your questions.
I am looking for implementation of CI/CD in to my current project here is what i think will work.
Environment consists of
- Jenkins
- git
- docker
- gradle
- Linux servers
- Sonar
- Ansible.
Each tool will be used as following.
Git:- Developers will push there code to this CVS.
Jenkins:- On detecting Check-in Jenkins will trigger a build and will deploy to one of the server.
Sonar:- will be used for code coverage and will check the code before building the same through Jenkins.
ansible:- ansible will be used to quickly prepare added nodes so that code can be deployed to them.
Docker in case if we need fresh test environments every time we can use docker+ ansible combo for doing the things.
Flow of work will be
User run unit test cases on his machine and commits the code to the server.
Jenkins will pull the code from git and will run sonar on the same and will generate reports.
jenkins will create build and will deploy the same on dev server.
A jenkins job will run and will perform the integration testing on the dev server
Any other automated tests can be run.
Finally builds pushed to next server using Jenkins.
I will use shell commands inside Jenkins to push compiled code from one server to another.
In my this scenario can some one answer me following.
Where will sonar get fit and how to use the same?
I see there are CD tools, cant i push compiled code to the servers using shell scripts written inside the Jenkins jobs to automatically deploy the things? What extra benefits a CD tool provides
Is is wise to create fresh test environment or we can keep using the old one again and again?
Will this complete CI/CD?
can someone share there implementation
You say you plan to use Git. I'll outline a scenario using Git on GitHub
Developers push code changes here as pull requests
The SonarQube GitHub Plugin kicks off an initial analysis of only the code changed in the PR looking for the introduction of new issues (note that coverage and duplications are not included in this check)
Once the PR is merged, Jenkins (in one job or several, depending on your needs)
builds
fires integration tests & any other automated tests
runs SonarQube Scan. Note that this comes last to include integration test results.
pushes build to next server
Note that the ability to break the build when the project doesn't pass the SonarQube Quality Gate you've set up may be desirable in your situation. Unfortunately, it's not available in the current server version: 5.2. It is available in 5.1, and is should return soon.
My development setup is such that for every svn checkin code is built,unit tested, packaged and published in Artifactory. Now I want to automate my deployment process & run integration(Selenium) test as part of this process. I am thinking of using Puppet to managed the deployment
Is puppet the correct tool for this
What is the process I should use to trigger puppet master to initiate a fresh installation on agents, I couldn't find any Jenkins plugin that would actually trigger puppet. One option is to call
puppet apply ...
as a Jenkins post build task
Any suggestions welcome, thank you.
Have a look at this Selenium Jenkins article from Saucelabs, a service that automates cross-browser testing. Though they are a vendor with a service to sell, the article covers how to do Selenium testing yourself with Jenkins. It also exposes common pain points you are likely to run into with this approach.
A Puppet master doesn't serve the function of orchestrating client convergences. Take a look at Mcollective. This is a tool that will allow you to trigger puppet runs on target systems from a Jenkins agent via script commands.

We are using Hudson as a CI tool. At present we are needed to use Jenkins, to deploy the build to Stage, Prod environment. What is the best aproach we should follow.
I know about promote buld plugin, but the issue is authentication. I want whevener we need to promote a build to deploy to Stage or Prod, it should ask for netqwork credential first. And then the promote job should execute the Batch command using the creadential supplied. At present, the promote plugin, runs using the credentials which the Tomcat server is configured to run.
Same issue with Build Pipeline plugin.
I want only dev or even hudson admin also should not be able to execute the promote build unless credential supplied. (We have windows 2008 r2 OS)
Can you please help me in resolving the issue. so that basically whenever a user click on Promote build to QA\Stage\Prod the plugin should ask for credential or should use the logged on users credential and execute the batch script using the logged users credential only and not by using the credentials of the account with which the tomcat server is configured.
Can you please help me?
Please suggests us the best aproach for making automated build on prod\stage.
For deployment I normally use SSH, Private/Public keys takes care of the authentication problems normally associated with running commands on other servers.
SSH is normally associated with unix based systems, but it does support windows.
Finally, I would recommend considering decoupling your build system (jenkins) from the system performing the deployment by using an intermediate repository. See the following answer for more details:
