Installing Constellation by using Docker
Explore the latest React-based run-time environment, which improves performance and responsiveness, and offers a revised set of user-friendly tools for authoring views and portals. You can use Docker to install the Constellation engine framework in your on-premises development environment.
- Pega Platform is hosted on Pega Cloud Services.
- Pega Platform is hosted on a client-managed cloud environment.
- Constellation was installed with Pega Infinity.
- Ensure that you have the Docker command line interface installed on your on-premises environment.
- Prepare docker authentication. For more information, see Configuring Docker authentication.
- Review the process of implementing Constellation on your system. For more information, see Setting up the Constellation service in Pega Platform.
Log in to Pega's Docker repository.
docker login pega-docker.downloads.pega.com/constellationui/service:8.6.0-rc-latest
In a terminal window, pull the Constellation container by entering docker pull pega-docker.downloads.pega.com/constellationui/service:8.6.0-rc-latest.
Start the service by entering docker run -v /<path to folder with key certificate>:/host_folder -p 3443:3443 --name <container name> pega-docker.downloads.pega.com/constellationui/service:8.6.0-rc-latest httpsKey=<SSL key> httpsCert=<SSL certificate> urlPath=<service URL path> port=3443 logLevel=infoThe variables have the following values:
docker run -p 3443:3443 -v /usr/abc/certs:/host_folder --name constellation-service pega-docker.downloads.pega.com/constellationui/service:8.6.0-rc-latest port=3443 urlPath=/c11n httpsKey=afile.key httpsCert=bfile.cert logLevel=infoWhen you deploy behind a load balancer, the load balancer usually holds the SSL certificate. In this case, you do not need to add the certificate at this point.
- <path to folder with key certificate> is the absolute path to the local folder that contains the HTTPS key file and the certificate file.
- <container name> is the name of the Docker container.
- <SSL key> is the name of the key file.
- <SSL certificate> is the name of the certificate file.
- <service URL path> is the URL path on which the service is deployed. The path must match the load balancer or router traffic routing.
