I deployed the marbles demo to bluemix. But I do not see its go fmt.println statements in the log.
How does a programmer print to the bluemix log?

Ken,
If you are using the built-in deploy (Demo Chaincode tab) it is going to install the Marbles code from the public GitHub repository appropriate for your Bluemix instance.
If you are looking for the fmt.println statements in the logs, you should make sure you are looking at the logs from the chaincode execution (Network tab), not the logs of the peers themselves.
If you are looking to edit the demo code to insert your own log statement at specific places, you will need to create your own fork of the public Marbles demo code and not use the built-in deployment. You can either run the Marbles application locally pointing to your Blockchain instance hosted on Bluemix or deploy your edited code to Bluemix as well. You should find additional instructions for those deploy paths in the Readme.md of the Marbles demo repository, depending on your preference. I would recommend running the application locally first.
Hope this helps!

I am almost done with my first Test Sveltekit Application and want deploy the App in the next Days in my private Network. When I google for this I get flooded with "Deploy to Vercel, Netlify.... and so on" but I dont see much for deploying it the Application to an Server.
Can somebody explain what to do? The Application uses Endpoints.
You would likely want to run it through a Node server, for this you can use the adapter-node package, see the documentation for it for more information.

I followed the instructions on IoT Asset Tracking on a Hyperledger Blockchain . BUILD and DEPLOY finished successfully, but I can't find the composer-rest-server- app under Cloud Foundry Applications.
I can use the CF Blockchain services, enter the Monitor and open the Swagger UI. The question is, where can I find the application-specific APIs mentioned in the tutorial:
If everything deployed correctly, you can find the app in the IBM Cloud dashboard at https://console.bluemix.net. If you have many apps and services deployed, make sure to filter correctly or to be aware of paging.
If you suspect that something got wrong during build and deploy, go to the toolchain and check the logs. The toolchains can also be reached from the dashboard.
There's lots of documentation and a kludgy console to set up continuous deployment in Cloud Foundry, but I haven't found any documentation on what the artifacts inside a repository need to be.
I don't want to cut-n-paste flows from the node red editor. If that's the only way, then IBM is not ready for prime time. I also am aware of most everything about my flows being in the Cloudant nodered db.
A node red application is more than the flows though. What about my _design docs for my dbs?
I need device info and other stuff from the Watson console, Cloudant info and my flows packaged up into something deployable.
Has anyone scripted this?
What I mean by this is I can clone a Docker project, an npm project and all sorts of projects that implement a build->test->push mechanism. They employ a configuration script of some sort (e.g. package.json) and contain a bunch of source files for the actual application, test scripts, db scripts, whatever is necessary to deploy the application and its environment into a host. I see lots of documentation on the toolchain and its features, but I'm not clear on if it's possible to make use of it for my hosted node red application. Or if I have to write the scripting mechanisms to offload flow info from the nodered db and query all my other dbs for their respective _design docs and all the other configuration information required to set up an IoT node red application.
I forgot to mention, the copy/paste method loses information; you get no tab level metadata. The only way to get all the flow stuff is to pull if from the nodered flow record.
Node-RED will release a new version in a couple of days that will introduce projects, so you'll be able to use GitHub and all the usual tools to handle your app: https://twitter.com/NodeRED/status/956934949784956931 and https://nodered.org/docs/user-guide/projects/
While it doesn't address your short-term needs, I think it's the best long-term solution. Hopefully that helps.
I'm starting out with IBM Bluemix and CloudFoundry. Using the tutorial examples of the Node.js/Cloudant app I have a dev workflow that seems really slow. What is the best practice for development with cf?
Here's what I do now
Edit my files locally
cf push myapp
Wait for a long time for the app to deploy
Test and find an error

If you are building a Node.js application, you can use Bluemix Live Sync to quickly update the application instance on Bluemix and develop as you would on the desktop without redeploying.
You can choose to download the bl cli to sync with a local directory using Desktop Sync, or set up your project on DevOps Services and edit the code directly in your browser using Live Edit. Look in the documentation for Bluemix Live Sync.
https://developer.ibm.com/devops-services/2015/02/13/everything-kitchen-sync-bluemix-live-sync/
If you are doing more intensive development, it would be faster for you to set up node locally and push to Bluemix periodically. You can still consume most Bluemix services locally.
If you have to rely on an architecture resident in Bluemix and you do not have the possibility to test on local you cannot avoid the "push" command and the workflow you described. Regarding point 3, you might have incurred in a platform issue announced at https://developer.ibm.com/bluemix/support/#status.
I am a newbie for the bluemix. I would like to start the Node red app. However the app will never be created, instead the screen always show Your application is staging. I have try this a number of times and changed the server location from UK to USA. However it never works.
it is a known issue about a node.js module not building correctly. There is already a fix about the module, we are waiting for the npm repository to be updated. https://github.com/ibmdb/node-ibm_db/pull/44/commits
Try to download the node-red code from the official GitHub then push it to Bluemix. Another thing that you could do is use the node-red inside a Docker and also push it to Bluemix.
