I have Kotlin pet-project with docker-compose file:
version: '3.1'
services:
app:
build:
context: .
dockerfile: Dockerfile
command: java -jar ./testapp.jar
ports:
- "8080:8080"
depends_on:
- postgres
environment:
- SPRING_DATASOURCE_URL=jdbc:postgresql://172.25.1.3:5432/kotlin-app
- SPRING_DATASOURCE_USERNAME=postgres
- SPRING_DATASOURCE_PASSWORD=Tolstochok3000
networks:
app-network:
ipv4_address: 172.25.1.2
postgres:
build:
context: docker/db
dockerfile: Dockerfile
command: postgres
environment:
POSTGRES_DB: "kotlin-app"
POSTGRES_USER: "postgres"
POSTGRES_PASSWORD: "Tolstochok3000"
ports:
- "5432:5432"
networks:
app-network:
ipv4_address: 172.25.1.3
restart: always
networks:
app-network:
ipam:
config:
- subnet: 172.25.1.0/16
I tried docker-compose up, postgres started without problem, but app throw exception: Factory method 'resourceHandlerMapping' threw exception; nested exception is java.lang.IllegalStateException: No ServletContext set
When I started application on localhost (without docker), application work correctly with db in docker.
Application dockerfile:
FROM gradle:jdk17 as builder
WORKDIR /test-kotlin-app
COPY src ./src
COPY build.gradle.kts ./build.gradle.kts
RUN gradle clean build
FROM openjdk:17-alpine as backend
WORKDIR /root
COPY --from=builder /test-kotlin-app/build/libs/* ./app
ENTRYPOINT ["java", "-jar", "/root/app"]
Application propeties:
#DATABSE SETTINGS
datasource:
driver-class-name: org.postgresql.Driver
url: ${SPRING_DATASOURCE_URL:jdbc:postgresql://localhost:5432/kotlin-app}
username: ${SPRING_DATASOURCE_USERNAME:postgres}

#JPA SETTINGS
jpa:

hibernate:

properties:

I tried change docker-compose file application.yml (remove variables) and try remove network, but it didn't help

CodePudding user response：
Perhaps your DB container is not yet ready when the app is initialized. You may want to implement some waiting mechanism like this or like some of the solutions here.
CodePudding user response：
I resolve problem, when fixed build section in build.gradle.kts file. Remove block tasks.withType and add build section with default spring boot builder:
tasks.named<org.springframework.boot.gradle.tasks.bundling.BootJar>("bootJar") {
mainClass.set("con.example.app.KotlinAppApplicationKt")
archiveBaseName.set("testapp")
archiveFileName.set("testapp.jar") }
