Gradle Docker tasks - postgresql

Question

For my local development tasks
1. i want to ensure that the DB is running in the docker container which in this case is Postgres, i have a bootRun task defined in my build.gradle file
bootRun{
jvmArgs = [
"-Ddb.host=jdbc:postgresql://localhost:5432/postgres",
"-Ddb.username=postgres",
"-Ddb.password=apgdb"
]
}
and docker installed on my machine i just want to ensure that i do not have to manually go and start the postgres image from terminal and then do a bootRun,
can we create a gradle task which can ensure that it restarts the postgres on every exit of bootRun and start everytime we spin the app.

Answer 1

I use the gradle-docker-compose plugin to achieve this kind of task. You can create a docker-compose.yml file that defines your postgres db:
services:
db:
image: postgres:11
ports:
- "5432:5432"
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: apgdb
POSTGRES_DB: postgres
And that would be the respective build.gradle file:
plugins {
id "com.avast.gradle.docker-compose" version "0.8.14"
}
dockerCompose {
database {
useComposeFiles = ['docker-compose.yml']
}
}
bootRun{
dependsOn 'databaseComposeUp'
jvmArgs = [
"-Ddb.host=jdbc:postgresql://localhost:5432/postgres",
"-Ddb.username=postgres",
"-Ddb.password=apgdb"
]
}
Now when you run gradle bootRun it will start up the database before spring boots up.
