Add Your Build and Deploy Pipeline Artifacts
The first step in Artifact Build and Deploy pipeline is to create a Harness Service. Harness Service connects to the Artifact Server you added in Harness Account Setup and identifies the artifact to deploy. The Service also contains the scripts used to install and run the build on the target nodes.

Before You Begin
Step 1: Create a Service
Harness Services represent your microservices/apps. You define where the artifacts for those microservices/apps come from, the container specs, configuration variables, and files for those microservices.
To create the Service, perform the following steps:
- In your Harness Application, click Services. To create a Harness Application, see Application Components.
- Click Add Service. The Add Services settings appear.
- In Name, enter a name for your Service. In this example, ToDo List WAR is used because ToDo List app is built and packaged it in a WAR file.
- In Deployment Type, select Secure Shell (SSH).
- In Artifact Type, select Web Archive (WAR).
- In Application Stack, select Standard Tomcat 8.
- Click Submit.
The new Service is created. There are several installations and start scripts added by default. When your application is deployed, these scripts run on the target host(s).
Next, Artifact Source is added.
Step 2: Add an Artifact Source
The Artifact Source defines where the Artifact Collection step looks for the built artifact during the Build Workflow. Also, the Service is used in the Deploy Workflow to install the artifact on the target host(s).
To add an Artifact Source, perform the following steps:
- In your Service, click Add Artifact Source, and select Jenkins. The Jenkins settings appear.
- In Source Server, select the Jenkins Artifact Server you set up in Harness Account Setup. Once you select the Source Server, the Job Name field loads all of the Jenkins jobs from the Source Server.
- In Job Name, select the job you want to run to build your artifact. Harness also supports Jenkins Multibranch Pipelines.
- Select the Meta-data Only setting. Typically, metadata is sufficient as it contains enough information for the target host(s) to obtain the artifact. Harness stores the metadata and, during runtime, the Harness Delegate passes the metadata to the target host(s) where it is used to obtain the artifact(s) from the source repo. Ensure that the target host has network connectivity to the Artifact Server.
- In Artifact Path, select the path and name of the artifact. In this example, target/todolist.war is used.
When you are done, the Jenkins Artifact Source will look something like this:
- Click Submit.
The Artifact Source is added to the Service.
Step: View Artifact History
Next, let's see the artifact history that Harness can pull from Jenkins.
- Click Artifact History.
- Click Manually pull artifact. The Manually Select An Artifact dialog appears.
- In Artifact Stream, select the artifact source you just added.
- In Artifact, select the build for which you want to view history.
- Click Submit.
- Click Artifact History again. The history for the build you specified is displayed.
For more information on Service settings, see Services.
Now, that the Service is complete, we can create the Build Workflow to build the next version of the artifact.
