How to run Jenkins with docker?

 

Sometimes no one wants to deploy and configure the whole server and applications. Especially when the time is the scarce resource. Developers know about it – they face this problem every day. One of the solutions is docker. It helps with deploying, provisioning and automating development and production environments without the big workload. Docker can help also with learning. You do not need the create separated virtual machines for your labs. The only one you need is docker and your own notebook/PC. Forget about long configuration processes and subsequent work expenditures (removing, cleaning etc.). If you want to learn some Jenkins, Continue reading

How to use credentials in Jenkins projects?

 

Some time ago I published a post in which I explain how you can create credentials in Jenkins. It’s very important topic because there are several ways to manage the credentials, but not all of them are safe.

It is caused by the Java (yes, I know, “it’s always Java!”). Jenkins has been using Java 8 since the 2.54 version, hence you may have problems if you still use Java 7. And it’s more than likely that Continue reading

Jenkins Windows slave agent as a service

 

Jenkins is a fantastic tool for automation every process in your company/lab/your own projects. You can integrate your PowerCLI scripts with Ansible and even more utilities. I won’t describe Jenkins, because the are tons of pages (and also its own Wikipedia) which do it better than me. I want to focus on one problem. Run Jenkins Windows slave agent as a service inside the operating system. Jenkins allows you to set up many workers. It can be a Linux as well as Windows machine.
