I am using Node-RED on IBM Bluemix. I am trying to connect to MySQL hosted by ClearDB, but I cannot find a suitable node in the database category.
How can I bind to existing ClearDB service that I already have bound to another app?
You can take a look at this MySQL node for Node-RED in the flow and node library, it is an extension. The steps to add additional node types to the editor is explained in the Node-RED documentation in general, however it does not directly apply to Bluemix. For your Bluemix environment you would need to access and modify the environment. See this post on how to deploy your customized Node-RED environment to Bluemix.

I used to test installed mongodb-shard on kubernetes by helm,but I found that those helm charts are not really a qualified mongodb shard.These helm charts can correctly create Pods with names like mongos-1 mongod-server-1 mongod-shard-1,this seems to be a correct shard cluster configuration, but the appropriate mongos, mongod server instance is not created on the corresponding Pod.They just create a normal mongod instance on the corresponding pod, and there is no connection between them.Do I need to add scripts to execute commands similar to rs.addShard(config)?Encountered the same problem when installing mysql cluster using helm.
What I want to know is, is it not appropriate to install mysql/mongodb cluster on kubernetes in general scenarios?Is the database installed independently or deployed on Kubernetes?
Yes, you can deploy MongoDB instances on Kubernetes clusters.
Use standalone instance if you want to test and develop and replica set for production like deployments.
Also to make things easier you can use MongoDB Enterprise Kubernetes Operator:
The Operator enables easy deploys of MongoDB into Kubernetes clusters,
using our management, monitoring and backup platforms, Ops Manager and
Cloud Manager. By installing this integration, you will be able to
deploy MongoDB instances with a single simple command.
This guide has references to the official MongoDB documentation with more necessary details regarding:
Install Kubernetes Operator
Deploy Standalone
Deploy Replica Set
Deploy Sharded Cluster
Edit Deployment
Kubernetes Resource Specification
Troubleshooting Kubernetes Operator
Known Issues for Kubernetes Operator
So basically all you need to know in this topic.
Please let me know if that helped.
I am aware that node APIs can be built on top of NoSQL DB can node API be built with MySQL DB? Please also share some good resources.
Node.js is Javascript server side runtime. So You can connect to all the data source you can with java/.Net etc. So yes, you can use MySql with node.js.

I'm deploying WSO2 API manager 2.6.0 with an external MySQL database and I'm trying to have my API's persist when I change my deployment.
Currently I have 2 deployments using the same external database, one local and the other hosted on an AWS EKS cluster. When I create an API on my local deployment, I can only view it on my AWS deployment if I'm logged in to the store, and visa-versa for my localhost deployment.
The expected and desired behaviour is that all APIs created on both deployments should be displayed on the store no matter if I'm logged in or not, is there any configurations I can change to make the happen?
Here is the doc I used to configure the external database: https://docs.wso2.com/display/AM260/Installing+and+Configuring+the+Databases
I need to connect a Bluemix organisation to multiple external systems.
Can I use one Cloud Integration service Basic connector on Bluemix to connect to many on-premises end-points?
Yes, you can use a single Basic connector to connect to multiple endpoints.
After you follow the instructions to get your connector set up, you'll want to click the arrow at the far right under the detail column:
From there, you'll be taken to a page that lists the endpoints setup with the basic connector. You can click the add endpoints button to add as many endpoints as you would like.
Keep in mind, even though you can connect to multiple endpoints with a Basic connector, you can only have one Basic connector at a given time.
Cloud Integration depends on your end points.
If you have ssh endpoint Basic Connector works but it has limitation of 5 Connection free. There after you are charged in Bluemix.
Where as if you are endpoints are API's suggested connector is Standard Connector as it works on https.
I'd like to create a build chain for open source projects I'm working on. I'm currently using github, travis and coveralls. This is working fine but I'd like to add some kind of static code analyze.
I was thinking about hosting SonarQube on openshift, but problem is that openshift does not allow remote connection to database.
I have come to following solutions, but none of them seems to be easy to achieve:
Any REST API for sonar that could be used instead of raw db access
Any alternative for sonar that could be hosted on openshift
Migrate from travis to jenkins hosted on openshift and use this
Any other (free) alternative to openshift which would allow raw db access
Any other option
1 would be an ideal solution but I've searched all sonar plugins I could find and haven't found any :/
Am I missing something? There is no easy way to host sonar without exposing db access?
It looks like at least one person has gotten SonarQube running on OpenShift using the DIY cartridge:
http://majecek.wordpress.com/2013/12/06/how-to-run-sonarqube-4-0-on-openshift/
I was able to get SonarQube to start following those instructions.
EDIT: databases in OpenShift applications are only exposed publicly in scaled applications. You will want to create your sonar app with the -s option if you need to populate your database from outside OpenShift.
