Execute SQL script on docker compose - mysql

Question

I have a project that runs when ./entrypoint.sh or docker-compose up is run from the root directory of project and generates the swagger API interface, but the calls return entry response no data.
If I run with MySQL on localhost without docker, works perfectly fine. How do I load the data?
entrypoint.sh
#!/bin/bash
docker network create turingmysql
docker container run -p 3306:3306 --name mysqldb --network turingmysql -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=tshirtshop -d mysql:5.7
docker-compose build
docker-compose up
DockerFile
FROM mysql:5.7
ADD ./database/tshirtshop.sql /docker-entrypoint-initdb.d
#### Stage 1: Build the application
FROM openjdk:8-jdk-alpine as build
# Set the current working directory inside the image
WORKDIR /app
# Copy maven executable to the image
COPY mvnw .
COPY .mvn .mvn
# Copy the pom.xml file
COPY pom.xml .
# Build all the dependencies in preparation to go offline.
# This is a separate step so the dependencies will be cached unless
# the pom.xml file has changed.
RUN ./mvnw dependency:go-offline -B
# Copy the project source
COPY src src
# Package the application
RUN ./mvnw package -DskipTests
RUN mkdir -p target/dependency && (cd target/dependency; jar -xf ../*.jar)

Answer 1

Do you have two Dockerfiles? Looks like you built your own MySQL container?
Otherwise, these shouldn't be part of your Java multi-stage build
FROM mysql:5.7
ADD ./database/tshirtshop.sql /docker-entrypoint-initdb.d
Assuming that you did build a separate image for mysql, in the Docker-Compose, you're not using it, as you're still referring to image: mysql:5.7
Rather than building your own, you should mount the SQL script into it
For example
mysqldb:
image: mysql:5.7
...
volumes:
- db-data:/var/lib/mysql
- ./database/tshirtshop.sql:/docker-entrypoint-initdb.d/0_init.sql
Then, forget the Java service for a minute and use MySQL workbench or the mysql CLI to verify that data is actually there. Once you do, then startup the API

Answer 2

If you copying sql scipt already to docker build then you do not need to mapped it again in the docker-compose, if you have docker-compose then you do not the bash script single command docker-compose up --build will do the job.
So modify your docker-compose as per your Dockerfile.
Dockerfile
FROM mysql
ADD init.sql /docker-entrypoint-initdb.d
docker-compose
version: '3.7'
services:
# App backend service
app-server:
# Configuration for building the docker image for the backend service
build:
context: .
dockerfile: Dockerfile
ports:
- "8080:8080" # Forward the exposed port 8080 on the container to port 8080 on the host machine
restart: always
depends_on:
- mysqldb # This service depends on mysql. Start that first.
environment: # Pass environment variables to the service
SPRING_DATASOURCE_URL: jdbc:mysql://mysqldb:3306/tshirtshop?useSSL=false&useLegacyDatetimeCode=false&serverTimezone=UTC
SPRING_DATASOURCE_USERNAME: root
SPRING_DATASOURCE_PASSWORD: root
networks: # Networks to join (Services on the same network can communicate with each other using container name)
- uringmysql
# Database Service (Mysql)
mysql:
build: .
environment:
MYSQL_ROOT_PASSWORD: root123
MYSQL_DATABASE: appdata
MYSQL_USER: test
MYSQL_PASSWORD: root123
volumes:
- db-data:/var/lib/mysql
tty: true
# Volumes
volumes:
db-data:
# Networks to be created to facilitate communication between containers
networks:
turingmysql:
Now just run
docker-compose up --build
this will build and up the container and you will not need to mapped the host init script, as it already in Docker image.
The directory structure will look like
Now you application will able to access DB using jdbc:mysql://mysqldb:3306/tshirtshop? this endpoint as both are in same network and can refer eacher other using name.

Thank you cricket_007 and Adii for the responses. They put me in the right direction. I want to document my experience and how the issue was resolved. New to dockerization so I was learning by practice. For anyone new to dockerization and having same issues in Spring Boot, MySQL and docker, this would surely help
First, my entrypoint.sh changed below. The docker-compose down is for restarts.
#!/bin/bash
docker-compose down -v
docker-compose up --build
Second, I had to use an existing mysql image instead of building one.
version: '3.7'
# Define services
services:
# App backend service
app-server:
# Configuration for building the docker image for the backend service
build:
context: .
dockerfile: Dockerfile
ports:
- "8080:8080" # Forward the exposed port 8080 on the container to port 8080 on the host machine
restart: always
depends_on:
- mysql # This service depends on mysql. Start that first.
environment: # Pass environment variables to the service
SPRING_DATASOURCE_URL: jdbc:mysql://mysql:3306/tshirtshop?useSSL=false&allowPublicKeyRetrieval=true&useLegacyDatetimeCode=false&serverTimezone=UTC
SPRING_DATASOURCE_USERNAME: turing
SPRING_DATASOURCE_PASSWORD: pass
networks: # Networks to join (Services on the same network can communicate with each other using their name)
- turingmysql
# Database Service (Mysql)
mysql:
image: mysql/mysql-server
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: tshirtshop
MYSQL_USER: turing
MYSQL_PASSWORD: pass
volumes:
- db-data:/var/lib/mysql
- ./database:/docker-entrypoint-initdb.d
tty: true
networks: # Networks to join (Services on the same network can communicate with each other using their name)
- turingmysql
# Volumes
volumes:
db-data:
# Networks to be created to facilitate communication between containers
networks:
turingmysql:
driver: bridge
Needed to specify that the network is a bridge. My sql file was mounted from a folder relative to docker-compose.yml. Also had to add allowPublicKeyRetrieval=true to my jdbc url. Created a user to access the database tshirtshop.
And here is the Dockerfile.
#### Stage 1: Build the application
FROM openjdk:8-jdk-alpine as build
# Set the current working directory inside the image
WORKDIR /app
# Copy maven executable to the image
COPY mvnw .
COPY .mvn .mvn
# Copy the pom.xml file
COPY pom.xml .
# Build all the dependencies in preparation to go offline.
# This is a separate step so the dependencies will be cached unless
# the pom.xml file has changed.
RUN ./mvnw dependency:go-offline -B
# Copy the project source
COPY src src
# Package the application
RUN ./mvnw package -DskipTests
RUN mkdir -p target/dependency && (cd target/dependency; jar -xf ../*.jar)
#### Stage 2: A minimal docker image with command to run the app
FROM openjdk:8-jre-alpine
ARG DEPENDENCY=/app/target/dependency
# Copy project dependencies from the build stage
COPY --from=build ${DEPENDENCY}/BOOT-INF/lib /app/lib
COPY --from=build ${DEPENDENCY}/META-INF /app/META-INF
COPY --from=build ${DEPENDENCY}/BOOT-INF/classes /app
ENTRYPOINT ["java","-cp","app:app/lib/*","com.turing.ecommerce.TuringApplication"]
to run, from root directory of project ./entrypoint.sh on mac and the rest is history.
