Web&Cloud

GCP frequent pbs:

• When cloud shell don't start:

  • https://shell.cloud.google.com/?show=ide%2Cterminal 

• When app is not well create

  • gcloud app create

Working in Lab with App Engine:

99% of problems in Lab is just coming from a bad configuration of proxy

• • • Eclipse need to access the web, maven need to access the web, they maybe not configured with proxy !!

    • For maven, you can just:

      • cp ~molli-p/.m2/settings.xml ~/.m2/

    • Eclipse should be ok (otherwise check preference and general/network)

The doc https://cloud.google.com/appengine/docs/?hl=fr (the root)

• • • carefull take the doc of *appengine*, many products on Gcloud

    • We use the standard environnement (not flexible) and Java 1.8

    • Entities: https://cloud.google.com/appengine/docs/standard/java/datastore/entities?hl=fr

    • queries: https://cloud.google.com/appengine/docs/standard/java/datastore/queries?hl=fr

Basically, we just need a Google Cloud SDK and Maven and Google Console

• • • mvn archetype:generate -Djava8=true -DCloudSDK_Tooling=false -Dappengine-version=1.9.76 -Dapplication-id=<your-id>  -Dfilter=com.google.appengine.archetypes:

• • An Eclipse with the Gcloud plugin will download the gcloud SDK for you

    • An eclipse with Gcloud plugin and proxy is installed in /media/Enseignant/eclipse

Example code

• • These project are created with maven. To import on eclipse, just import an existing maven project.
