在heroku上使用mongodb部署jhipster网关

Question

Using jhipster 5.7.2.

I'm trying to deploy a gateway created with jhipster to heroku as per the documentation

The gateway is using mongodb and works on my machine. Tested the app directly with a local mongodb as well as with docker-compose. All of it works well.

Then I tried deploying it on heroku :

jhipster heroku

But it failed to start :

2019-01-07T23:37:16.326055+00:00 app[web.1]: java.lang.IllegalArgumentException: Invalid argument syntax: --spring.data.mongodb.database=

As I see it in the console, the complete command heroku execute is :

`java $JAVA_OPTS -Xmx256m -jar target/*.war --spring.profiles.active=prod,heroku,no-liquibase --server.port=4838 --spring.data.mongodb.database=$(echo "$MONGODB_URI" | sed "s/^.*:[0-9]*\///g")`

From here I'm not sure where to go next. Was it supposed to work all out of the box or do I miss some steps ? I suppose I should install myself the mongodb on heroku but I'm not sure. Any related advice on hosting jhipster microservices architecture are also welcome.

Thanks in advance :)

UPDATE : Indeed, the environement variable 'MONGODB_URI' mentionned in the deploy command is not set on the server. At this point I assume I should create manually a mongodb server and the set this variable ?

Answer 1

You have to install the MongoDB add-on for your Heroku application which you can do on the Heroku page or by running:

heroku addons:create mongolab

After that, the environment variable MONGODB_URI will be set.
