If Corda is permissioned, how does it ensure correct consensus?
Take a look at the Corda documentation on notaries. You can configure the type of consensus you want from the notary and how rigorous you want your transaction validations will be.
I’m having trouble with connecting to my Corda nodes
The best thing to do is ensure that you have set up your development environment to ensure you can properly compile and run your CorDapps.
How does Corda work internally?
Corda runs several services within it to enable all of Corda’s features.
You can find more information about Corda’s internal services in the documentation.
Can I run Corda in Docker?
If you’ve never set up Corda with docker before, take a look at this 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:

Can I use a custom SQL database with Corda in production?
Yes. Corda ships with H2 as an internal database but you can customize it to support tools like Azure SQL, SQL Server, Oracle, and PostgreSQL. Here’s our documentation on how to configure it.
You may also want to look at this recent blog post on CorDapp development from a database perspective.

Membership Attestation on Corda
In this live stream, we’re going to demonstrate some of Corda’s new features for membership attestation. Membership attestation allows you to create and isolate permissions at the application level, which can be really powerful in terms of organizing your network participants.
We’ll do a short recap of Corda and then look over the typical use cases for membership attestation in a Corda network. Once we’ve laid out the intuition we’ll look at an example CorDapp so you can see these features used in practice with a demo.
