Feature Request - Google App Engine Generator

saturnism commented 6 years ago

Overview of the feature request

Add a generator to prepare app for deployment into Google App Engine Standard Java 8.

Motivation for or Use Case

GAE is a PaaS that can deploy a single module or multiple modules (services) easily. It also has SSL support for both *.appspot.com domain and custom domain too. This feature can prepare existing JHipster apps for deployment into GAE.

MVP Support Proposal

[x] Monolith
- [x] Generate appengine-web.xml (Done #7765)
- [x] Enable session store (Done #7765)
- [x] Add App Engine plugin to pom.xml (Done #7765)
- [x] Add App Engine plugin for Gradle
- [x] Generate/update application properties to use Google Cloud SQL (Done #7765)
- [x] Documentation (Done, https://github.com/jhipster/jhipster.github.io/pull/630)
[ ] CI/CD
- [ ] Generate Travis File for GAE
- [ ] Documentation
[ ] Micorservices
- [x] Microservices - all of the monolith features (Done #7765)
- [ ] Gateway
- [ ] Generate dispatch mapping to let App Engine route microservices request.
- [ ] Documentation

Not supported in MVP proposal:

No registry/zuul support - App Engine supports request mapping already.
Support only MySQL for now, and possibly PostgreSQL - CloudSQL.
[x] Checking this box is mandatory (this is just to show you read everything)

@jdubois what's the recommended way to do this? e.g., for each app, we need to add:

appengine maven plugin
WEB-INF/appengine-web.xml
Update production DB URI

Would it make sense to add this option directly into the app generator? Or, is there a way to modify existing files via a new generator, like jhipster appengine?

saturnism commented 6 years ago

i'll try w/ jhipster appengine, that tries to generate new profile/config

ruddell commented 6 years ago

I would recommend modeling it off of the Heroku subgen (or one of the other deployment options)

For adding a maven plugin, there are needles you can insert at in the pom.xml such as  with the corresponding method, here's how the Heroku generator modifies the pom
For updating production database URIs, the Heroku subgenerator adds an application-heroku.yml and a maven profile

sendilkumarn commented 6 years ago

This can be done without adding a new needle and jhipster appengine sounds perfect (for me)

jdubois commented 6 years ago

Yes @ruddell is right - the Heroku sub-gen is very close to what you want, and it's also very good, so it's the best way to start. I wouldn't worry too much about microservices yet, as soon as you have monoliths the rest will be very simple. Basically, a JHipster microservice is a monolith without a front-end (and that's super-easy to delete) and with Spring Cloud (and there's a big part of it you don't need, I think).

deepu105 commented 6 years ago

@saturnism jhipster appengine might be a bit too ambiguous. I would suggest jhipster gcp or jhipster google-app-engineorjhipster gae` or something similar

jdubois commented 6 years ago

yes +1 for jhipster gae as that's how I usually call app engine

ludoch commented 6 years ago

jhipster appengine-standard ? Flex would be a different one...

saturnism commented 6 years ago

i think jhipster appengine-standard is a too long though :(

saturnism commented 6 years ago

what if we do jhipster gcp, and it prompts you to see whether you want App Engine Standard, or GKE, etc. We can add more options over time.

The basic information we need is the project ID, and ensure that gcloud is installed.

jdubois commented 6 years ago

Yes jhipster gcp is good, and then you have multiple deployment options - those could also be sub-generators, but they would have some common code (which is logical, at least ensuring that gcloud is correctly set up)

saturnism commented 6 years ago

at the end of the day though, gke deployment is very different from appengine deployment. I think jhipster gae still makes more sense.

saturnism commented 6 years ago

Quick question, is there a way to update the production JDBC URL from my generator? I.e., w/o overriding w/ additional profile nor env vars.

PierreBesson commented 6 years ago

Maybe create a gae spring profile and add an application-gae.yml in resources/config.

saturnism commented 6 years ago

creating the profile doesn't mean it'll be used :( it still require ways to indicate that the profile is active.

the only way i can do this now is to build w/ additional profile, e.g. mvnw package -Pprod,prod-gae

PierreBesson commented 6 years ago

An other option is to modify the application-prod.yml directly. You can use the jsyaml lib or some regex fu to edit the file from your subgen.

PierreBesson commented 6 years ago

Just thought about something, maybe you can try adding a spring.profile.includes=gae in application-prod.yml.

Really not sure about this as the profile.include behavior used to be strange.

saturnism commented 6 years ago

nice! that's a good call since we are using spring boot 2 :) https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-profiles.html

PierreBesson commented 6 years ago

The GAE support issue is only lacking documentation to be closed. Reminder for @ludoch and @saturnism to PR to jhipster/jhipster.github.io.

jdubois commented 6 years ago

Yes let's only have monoliths for the moment -> for micorservices or more complex stuff we have far less users, and for them Kubernetes is also a good solution.

-> @ludoch @saturnism I'll try it today but unfortunately you're the only ones who can the documentation, I'm afraid.

jdubois commented 6 years ago

I did a few tests on this:

I fixed a small issue at https://github.com/jhipster/generator-jhipster/commit/78318d79240ba228f1e7863a4a19ad4b25b63b85
On first deployment I add an error because the SQL database wasn't created, I think it's mostly a documentation issue

And then when I deployed I had a huge stacktrace, here it is below. So there's still some work to do here, before releasing it.

PierreBesson commented 6 years ago

@ludoch @saturnism Documentation is crucially missing for this, our statistics is reporting that the GAE sub-generator has been used 0 times in the last month ! It doesn't even show up in the graph.

https://start.jhipster.tech/#/statistics

saturnism commented 6 years ago

:( added initial doc pr.

@jdubois i have a feeling that's multi-release jar causing issues.. :( /cc @ludoch

ludoch commented 6 years ago

Multi release jar issue will be fixed soon in a new cloud SDK release (ETA Wed Oct 10th)

saturnism commented 6 years ago

Cool. Let's test and release the doc PR after the multi-release JAR issue is fixed.

pradeepmanshajha commented 6 years ago

Any progress on gae subgenerator?

saturnism commented 6 years ago

@pradeepmanshajha the generator for monolith is actually already useable. just waiting for a new fix that can fix issues introduced by multi-release jar. is there a specific feature you are looking for?

initfusion commented 6 years ago

@saturnism i think this subgenerator is not supported with gradle project.

@initfusion ah you are right, we didn't add gradle plugin! will add it to the todo.

could i trouble you to share the generated appengine-web.xml? Thanks!

saturnism commented 6 years ago

@initfusion pls see if #8616 helps fix your issue. It's necessary for ehcache, but not necessary for hazelcast. But will add it by default just in case.

@saturnism this is my appengine-web.xml generated by maven project.

@initfusion got it; this is fixed in #8616, there are a few additional lines that need to be added. See: https://github.com/jhipster/generator-jhipster/blob/b301f1492a439a832c613b9f54280e150c26f900/generators/gae/templates/appengine-web.xml.ejs

Closing it as discussed privately with @ludoch

mguyaux commented 5 years ago

@saturnism with JHipster 6.2.0 i had the same stacktrace on App Engine with javax.cache.spi.CachingProvider: Provider org.ehcache.jsr107.EhcacheCachingProvider could not be instantiated Solved by changing appengine-web.xml to : (cache-api from 1.1.0 to 1.1.1)

<class-loader-config>
        <!-- temporary workaround to make sure the app uses it's memcache/mail jars.!-->
        <priority-specifier filename="cache-api-1.1.1.jar"/>
        <priority-specifier filename="javax.mail-1.6.2.jar"/>
</class-loader-config>

I'm not 100% sure it's accurate with a sample JHipster 6.2.0 app because I had the problem on an app that I upgrade since JHipster 5.3.1.

samyomar commented 4 years ago

Is this feature still available ? in the documentation on https://www.jhipster.tech/gcp/ it say that jhipster gae support only java 11. Any way to deploy on standard environment with Java 8 ?

SudharakaP commented 4 years ago

@samyomar : The Java 8 deployment on App Engine is a bit different in its configuration than Java 11 and unfortunately the GAE generator do not support Java 8 (i.e: we have upgraded to Java 11). If you want to deploy with Java 8 you will have to write your own appengine-web.xml deployment configuration. Since we were using Java 8 before, you can always refer to our previous appengine-web.xml deployment files.

samyomar commented 4 years ago

thank you @SudharakaP for the reply. I followed all these steps but the problem just resolved only when I removed the ApplicationWebXml class that jhipster create by default. as this class already extends SpringBootServletInitializer

summary, it worked when I have only one class called "ServletInitializer" and extends SpringBootServletInitializer.

SudharakaP commented 4 years ago

@samyomar : Thanks for the information. If you'd like feel free to add it to the documentation so that anyone who wants to deploy with Java 8 will know the process.
