Corda Bi-Weekly FAQ’s #2

Occasionally we look to take some of the feedback we get most often and see if we can provide tips to help developers with everyday issues.

Occasionally, we look to take some of the feedback we get most often and see if we can provide tips to help developers with everyday issues. This week, we had a couple of questions where a developer was trying to set up a CorDapp to run using docker. 

 

We get these kinds of questions all the time, so I’ll collect some of our resources on the subject to hopefully make things a little easier. 

 

The short answer is that docker does support Corda; we have our official docker image online here. You can also find our quick guide for how to run it here. The docs will always be updated with directions for the latest versions of Corda open-source and Corda enterprise.  

 

If you’ve never set up Corda with docker before, take a look at my beginner post on how to get a CorDapp running with docker. Or you can take a look at this post from Ashutosh, another developer evangelist, as well. 

 

When building a Corda node, you can specify that the files created are for docker-compose instead of using the local network bootstrapper. Note that this is through the dockerform Gradle task instead of the cordform task. You can essentially swap ‘dockerform’ and ‘cordform’ in your Gradle file and specify the image as the two tasks take nearly the same input. More on the dockerform and cordform tasks here in the docs. 

 

If you’re interested in going further on this sort of thing, our most recent sample (as of Corda 4.7) is the Bank in a Box CorDapp. It uses Kubernetes, helm, and docker for a state of the art corda container setup! 

 

Here once again are the links to the resources I mentioned, along with some other ones you might be looking for: 

 

• Link to the Bank in a Box CorDapp 
• Corda Enterprise Network Manager Deployment with Docker, Kubernetes, and Helm charts
• Link to the docs page on how to run the official Corda docker image
• Another sample Corda Kubernetes Deployment Code Example 
• Notes on the dockerform and cordform tasks in the docs  
• Here’s my post for beginners on getting CorDapps running in docker 
• Another great post from my colleague Ashutosh on containerizing Corda  

 

Hopefully, this is helpful and good luck with your builds!
