A while back I found a great tutorial on deploying Hyperledger Composer apps to IBM Cloud Blockchain starter plan at https://developer.ibm.com/tutorials/cl-deploy-blockchain-starter-plan-network/
But for some reason this tutorial isn't available any more.
Does anybody know of a good alternative?

I got a query to ask you all. I am looking for guides that help me deploy my spring boot application on google cloud computer engine, I type in my instance IP address when I test my spring boot application I unable to access it in REST API.
May I know do you have any guides or steps for me to follow to deploy successfully in google cloud computing engine. Why do I need to deploy in computer engine is because I deployed my angular at it and I deploy it both it seems that my angular project being replaced by my spring boot application.
Codelabs GCP / Spring series has deployment tutorials:
https://codelabs.developers.google.com/spring/
GCP has some "Getting Started" tutorials you can use here:
https://cloud.google.com/java/docs/
where the specific one for deploying a java app to GCE is here:
https://cloud.google.com/java/docs/tutorials/bookshelf-on-compute-engine
But the basic steps are as follows:
Write your Spring app
Build your Spring app
Run / test your jar locally
Push your jar to a location in Storage
Create a startup script for your GCE instance
Create a new GCE VM which uses your startup script using Console, Deployment API, or gcloud tool
After that, you need to ensure you have the proper network rules in place to be able to access your API publicly. If you do not wish to learn how to use GCE, I would suggest you look into using App Engine instead because then you do not need to learn how to deploy and instead can concentrate on your api. Here is a guide to do that
Currently I'm working on a Spring Boot 2 project where we use Heroku as our Cloud Service. We push our changes to Github and our instance on Heroku cloud gets provisioned and deployed. After participating Javaday in my city, I attended to a speech and got to know about this amazing framework, Keycloak. After some investigation, we have decided using Keycloak as our identity and access management.
From what I understand, we need to start a Keycloak standalone server as explained here https://www.keycloak.org/docs/latest/server_installation/index.html.
But the problem is, we cannot access to filesystem on Heroku instance and thus, cannot extract the Keycloak files and start the server.
I tried to follow these steps https://github.com/yurtsevich/keycloak-swarm-heroku yurtsevich has provided but I noticed that latest version of Keycloak Swarm is not compatible with Spring Boot 2.
Can we start Keycloak server on the same Heroku instance we have? I'm unable to find any solution to this at this moment.
Edit: this button from readme will deploy Keycloak on Heroku with free dynos: https://github.com/sannonaragao/keycloak-heroku
This button deploys the lastest version straight to Heroku.
https://elements.heroku.com/buttons/mieckert/keycloak-heroku
Beware! It deploys at the Performance-M dyno, you must change to free right after if you don't want to pay some use fee.
Is there a straightforward way to run WSO2 API Manager on Heroku? I've been through the basic Heroku docs on how to deploy Java applications and understand that process but it seems like jumping through hoops that maybe aren't needed.
I'd like to be able to simply upload the installed application (binary version of application) and a procfile that defines the bootstrap class file as the starting point.
Is this possible? Is there another way to get Java apps to run in Heroku without defining a pom.xml and having it build the application prior to deployment?
Thanks,
Dave
WSO2 offers the hybrid API model to deploy your WSO2 API gateway on Heroku and use WSO2 API Cloud to manage your APIs.
You can use WSO2 WSO2 Heroku Add-on which can be used as WSO2 API publisher and Store. Then use Heroku Button to deploy WSO2 API Gateway on Heroku.
More info: https://devcenter.heroku.com/articles/wso2apicloud
It looks like there is no straightforward way to run WSO2 API Manager on Heroku. I looked at how Java programs are run on Heroku and it seems your requirement cannot be achieved currently. Heroku seems to be depending on Maven projects.
WSO2 API Manager product is built from WSO2 Carbon platform, which is not a simple Maven Java project.
Heroku also runs the Java application on OpenJDK, which is not supported by WSO2 API Manager. Only Oracle JDK is supported as mentioned in Installation Prerequisites.
I hope this helps.
I have a spring application based on Spring 3.0 for rest web services.I was planning to deploy it to heroku but facing a lot of issues.Can someone tell me some free hosting or even paid hosting where i could deploy my application?
Forgive me for my inexperience at server side
Thanks
Cloudbees is a great PaaS product that offers you a Tomcat/MySQL infrastructure for your applications. I've tried the free version and I had no problems at all.
The other popular choice is go with Amazon Elastic Beanstalk, but I haven't used it yet (mainly because of the price). A nice comparison between popular PaaS products can be found in this DeveloperWorks article.
I am trying to get the idea of cloud serves but didn't get the point of that.
Dose it can replace a server for the app?
what is the purpose of it?
I have an android app and I what to get info from the server can it be done with Cloud Foundry and what is spring and how it connects to Cloud Foundry.
If you can give me link of how to communicate android app with Cloud Foundry
thanks a lot!
CloudFoundry's an open-source PaaS (github.com/cloudfoundry). It commoditizes the stack - that is, in practical terms, it makes it dead simple to get things like databases (MySQL, PostgreSQL, Redis, MongoDB), messaging (RabbitMQ), and web servers (Tomcat) up and running quickly. Whereas clouds like AWS let you spin up CPUs and hard disks and a stock OS install, a PaaS like CloudFoundry lets you spin up infrastructure, like message brokers, databases, and web servers and routers. So, yes, it replaces a server (or, often more importantly, it can stand in for 1000 servers on-demand). That's the obvious part.
CloudFoundry itself is open source, so unlike other PaaS solutions, by building on top of CF you're not locked into CF. You can later decide to run the cloud locally on your own datacenter, or on some other CloudFoundry provider (CloudFoundry.com is just one provider of the CloudFoundry software. Just as you can easily re-target a git repisotry to have it point to any remote repository using the git command line tool, you can re-target the CloudFoundry 'vmc' command line tool to point to a different CloudFoundry install.
Spring's a development framework in Java. It's not the only way to consume CF, but I personally think it's quite nice. CF exposes a lot of different technologies for the eager technologist and Spring provides the only comprehensive library set that can handle all those options. Learn one Spring library and the others will feel simialar, and so it's more natural to get started with a new API and technology. In the way that APIs designed with idiomatic Python APIs are said to be "Pythonic," Spring's APIs are cohesive and work nicely together. However, if Java's not your cup of tea (punny!), then that's OK too. CloudFoundry supports Ruby on Rails, Scala, Node.js, and other cloudfoundry providers support alternatives (Stacato supports Python, AppFog supports PHP, etc.)
For a quick example demonstrating how to get started with Spring, and the SpringSource Tool Suite, and a development virtual machine for CloudFoundry (so you can develop locally and quickly), check out this blog (and, particularly, the video embedded therein): http://blog.springsource.com/2011/08/24/micro-cloud-foundry-for-spring-developers/
The Springsource team has been doing some interesting work this year integrating a variety of Spring projects with Cloud Foundry.
With the rising popularity of microservices, many of the Spring projects are proving to be useful not only for quickly developing these smaller, lighter weight services, but also for easily incorporating some of the projects from Netflix OSS that implement patterns for making them industrial strength even at web scale.
A few related links:
The latest Cloud Foundry Java buildpacks include support for Spring
Boot and Spring Auto-reconfig (https://github.com/cloudfoundry/java-buildpack/releases).
The CF docs
contain an example on deploying Spring Boot apps to Cloud Foundry or
Heroku
The new Spring Cloud project will "Integrate your application with Pivotal Cloudfoundry. Makes it easy to implement SSO and OAuth2 protected resources, and also to create a Cloudfoundry service broker."
I look forward to seeing more of the results from the collaboration between the Cloud Foundry and Spring teams. One evidence of this is a recent tweet from Pivotal's James Watters "As the Microservices trends take off its pretty amazing to have the world's leading lightwieght #springframework on same team as CF."
