No ServletContext set. Problem with connection to DB in another container

Question

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}
    password: ${SPRING_DATASOURCE_PASSWORD:Tolstochok3000}
  #JPA SETTINGS
  jpa:
    show-sql: 'true'
    hibernate:
      ddl-auto: none
    properties:
      hibernate:
        dialect: org.hibernate.dialect.PostgreSQLDialect

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

May be link on projcet can help: https://github.com/NikRomanov3000/test-kotlin-pet-app — Nikita Romanov, Nov 09 '22 at 22:34
unrelated but changing `jdbc:postgresql://172.25.1.3:5432/kotlin-app` to `jdbc:postgresql://postgres:5432/kotlin-app` and removing all that networking stuff would rule out some number of configuration errors. — Colton, Nov 09 '22 at 23:03
I think there's insufficient information here to help. You've provided neither the full stack trace nor the `Dockerfile` from the springboot project, therefore it may not be possible to assist. — Colton, Nov 09 '22 at 23:06
@Colton I tried remove all network block and change jdbc:postgresql://172.25.1.3:5432/kotlin-app to jdbc:postgresql://postgres:5432/kotlin-app but it didn't help. — Nikita Romanov, Nov 10 '22 at 08:06
@Colton Also thank you for the comment. I added stacktrace and app dockerfile to description — Nikita Romanov, Nov 10 '22 at 08:11

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") }

This solution resolves same propblem for me. But I use just tasks.named("bootJar"), otherwise i get error. – AnEi Nov 23 '22 at 11:09

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.

I tried add condition : depends_on: postgres: condition: service_healthy But it doesn't work. Same error: No ServletContext set – Nikita Romanov Nov 09 '22 at 22:22

No ServletContext set. Problem with connection to DB in another container
