With this change the users of the Corda AIO image can decide which nodes to launch (A,B,C,Notary) exactly. Adds scripts to launch individual nodes as needed. Before this we could only launch all the nodes at once which did not work out well because it caused race conditions in the cordapp jar deployment code. This revision is tagged in the container registry as: hyperledger/cactus-corda-4-6-all-in-one-obligation:2021-03-19-feat-686 Fixes hyperledger-cacti#686 Signed-off-by: Peter Somogyvari <peter.somogyvari@accenture.com>
Implements transferring the cordapp jar files onto Corda nodes via SSH+SCP. It supports deploying to multiple nodes in a single request via an array of deployment configuration parameters that the caller can specify. Credentials are travelling on the wire in plain text right now which is of course unacceptable and a follow-up issue has been created to rectify this by adding keychain support or some other type of solution that does not make it necessary for the caller to send up SSH and RPC credentials with their deployment request. Another thing that we'll have to fix prior to GA is that right now there is no SSH host key verification. For development mode Corda nodes: There's possibility to declare which cordapp jar contains database migrations for H2 and the deployment endpoint can run these as well. The graceful shutdown method is implemented on our RPC connection class because this is not yet supported on the version of Corda that we are targeting with the connector (v4.5). The new test that verifies that all is working well is called deploy-cordapp-jars-to-nodes.test.ts and what it does is very similar to the older test called jvm-kotlin-spring-server.test.ts but this one does its invocations with a contract that has been built and deployed from scratch not like the old test which relied on the jars already being present in the AIO Corda container by default.
