Pipeline nodes are the physical machines that host one or more pipeline processes. The pipeline node is where you install and start the pipeline executable that runs the pipeline processes.

What is a node in Jenkins pipeline?
Node. A node is a machine which is part of the Jenkins environment and is capable of executing a Pipeline. Also, a node block is a key part of Scripted Pipeline syntax.
What is the difference between node and pipeline?
1 Answer. The simple answer is, Agent is for declarative pipelines and node is for scripted pipelines. In declarative pipelines the agent directive is used for specifying which agent/slave the job/task is to be executed on.
What is a node in Jenkins?
Node. A machine which is part of the Jenkins environment and capable of executing Pipelines or Projects. Both the Controller and Agents are considered to be Nodes. Project. A user-configured description of work which Jenkins should perform, such as building a piece of software, etc.
What is node and stage in Jenkins pipeline?
node specifies where something shall happen. You give a name or a label, and Jenkins runs the block there. stage structures your script into a high-level sequence. Stages show up as columns in the Pipeline Stage view with average stage times and colours for the stage result.
What is SH in Jenkins?
sh: Shell Script script. Runs a Bourne shell script, typically on a Unix node.
What does sh mean in Jenkins?
Jenkins has a number of plugins for invoking practically any build tool in general use, but this example will simply invoke make from a shell step ( sh ). The sh step assumes the system is Unix/Linux-based, for Windows-based systems the bat could be used instead.
What is agent in pipeline?
agent. The agent directive specifies where the entire Pipeline, or a specific stage, will execute in the Jenkins environment depending on where the agent directive is placed.
What is Multibranch pipeline in Jenkins?
The Multibranch Pipeline project type enables you to implement different Jenkinsfiles for different branches of the same project. In a Multibranch Pipeline project, Jenkins automatically discovers, manages and executes Pipelines for branches which contain a Jenkinsfile in source control.
What is DSL in Jenkins pipeline?
DSL stands for Domain Specific Language. You can describe your jobs in Jenkins using a Groovy Based Language. Groovy– It’s similar to java but simpler because it’s much more dynamic. It”s Scripting Language.
Why we use nodes in Jenkins?
If you are working on multiple projects, you may run multiple jobs on each project. Some projects need to run on some nodes, and in this process, we need to configure slaves. Jenkins slaves connect to the Jenkins master using the Java Network Launch Protocol.
What is Jnlp in Jenkins?
JNLP( JAVA NETWORK LAUNCH PROTOCOL ) is used to Connect to/launch your java application( here Jenkins) from a remote location. Go to Manage Jenkins -> Configure Global Security -> under Agents section -> TCP port for inbound agents -> select Random ->Save.
What is SCM in Jenkins?
In Jenkins, SCM stands for ” Source Code Management “. This option instructs Jenkins to obtain your Pipeline from Source Control Management (SCM), which will be your locally cloned Git repository.
What is difference between step and stage?
As verbs the difference between stage and step is that stage is to produce on a stage, to perform a play while step is to move the foot in walking; to advance or recede by raising and moving one of the feet to another resting place, or by moving both feet in succession.
What is label in Jenkins?
When creating a new slave node, Jenkins allows us to tag a slave node with a label. Labels represent a way of naming one or more slaves. We leverage this labeling system to tie the execution of a job directly to one or more slave nodes.
What is difference between Scriptline and declarative pipeline?
Declarative pipelines break down stages into individual stages that can contain multiple steps. Scripted pipelines use Groovy code and references to the Jenkins pipeline DSL within the stage elements without the need for steps.
