container not building with mentioned dockerfile - multiple containers - mysql

Question

I am working with a case where there is a main kernel application that uses mysql and influxdb as the databases and grafana for showing the data pictorially. I am creating separate containers for each using docker-compose and individual Dockerfiles.
The folder structure is as such :
dockercompose
docker-compose.yml
kernel
Dockerfilekernel
app.war
sqldb
Dockerfilesqldb
dump.sql
startup.sh
grafana
Dockerfilegrafana
grafana.env
run.sh
tsdbdb
Dockerfiletsdb
influxdb.env
init-influxdb.sh
entrypoint.sh
The container for kernel builds but on checking the logs, it is displaying the logs of influxdb, the same that displays on checking the logs for tsdbdb container.
Code for docker-compose :
version: '3'
services:
mysqldb:
build:
context: ./sqldb
dockerfile: Dockerfilesqldb
container_name: sql
command: mysqld --user=root --verbose
volumes:
- ./sqldb:/app/sql
restart: always
expose:
- "3306"
ports:
- "3306:3306"
environment:
- MYSQL_ROOT_PASSWORD=secretpassword
- MYSQL_DATABASE=dbtest
- MYSQL_USER=user
- MYSQL_PASSWORD=password
- MYSQL_ALLOW_EMPTY_PASSWORD=yes
tsdbdb:
build:
context: ./tsdbdb
dockerfile: Dockerfiletsdb
container_name: influx
restart: always
expose:
- "8083"
- "8086"
ports:
- "8083:8083"
- "8086:8086"
volumes:
- ./tsdb:/app/tsdb
env_file:
- './tsdbdb/influxdb.env'
grafana:
build:
context: ./grafana
dockerfile: Dockerfilegrafana
container_name: grafana
env_file:
- './grafana/grafana.env'
expose:
- "3000"
ports:
- "3003:3000"
links:
- tsdbdb
web:
build:
context: ./kernel
dockerfile: Dockerfilekernel
container_name: kernel
restart: always
expose:
- "8080"
ports:
- "8082:8080"
depends_on:
- mysqldb
links:
- tsdbdb
- mysqldb
volumes:
- ./kernel:/app/kernel
Dockerfile of kernel :
FROM java:openjdk-8-jre-alpine
ENV JHIPSTER_SLEEP 0
WORKDIR /app/kernel
# add directly the war
ADD *.war /app/kernel/app.war
RUN sh -c 'touch /app/kernel/app.war'
VOLUME /tmp
EXPOSE 8080
CMD echo "The application will start in ${JHIPSTER_SLEEP}s..." && \
sleep ${JHIPSTER_SLEEP} && \
java -Djava.security.egd=file:/dev/./urandom -jar /app/kernel/app.war
Dockerfile for influxdb, just in case :
FROM buildpack-deps:stretch-curl
WORKDIR /app/tsdb
RUN set -ex && \
for key in \
05CE15085FC09D18E99EFB22684A14CF2582E0C5 ; \
do \
gpg --keyserver ha.pool.sks-keyservers.net --recv-keys "$key" || \
gpg --keyserver pgp.mit.edu --recv-keys "$key" || \
gpg --keyserver keyserver.pgp.com --recv-keys "$key" ; \
done
ENV INFLUXDB_VERSION 1.2.4
ENV INFLUXDB_ADMIN_PASSWORD secretpassword
ENV INFLUXDB_DB master_db
RUN ARCH= && dpkgArch="$(dpkg --print-architecture)" && \
case "${dpkgArch##*-}" in \
amd64) ARCH='amd64';; \
arm64) ARCH='arm64';; \
armhf) ARCH='armhf';; \
armel) ARCH='armel';; \
*) echo "Unsupported architecture: ${dpkgArch}"; exit 1;; \
esac && \
wget -q https://dl.influxdata.com/influxdb/releases/influxdb_${INFLUXDB_VERSION}_${ARCH}.deb.asc && \
wget -q https://dl.influxdata.com/influxdb/releases/influxdb_${INFLUXDB_VERSION}_${ARCH}.deb && \
gpg --batch --verify influxdb_${INFLUXDB_VERSION}_${ARCH}.deb.asc influxdb_${INFLUXDB_VERSION}_${ARCH}.deb && \
dpkg -i influxdb_${INFLUXDB_VERSION}_${ARCH}.deb && \
rm -f influxdb_${INFLUXDB_VERSION}_${ARCH}.deb*
COPY influxdb.conf /etc/influxdb/influxdb.conf
EXPOSE 8086
VOLUME /var/lib/influxdb
COPY entrypoint.sh /entrypoint.sh
COPY init-influxdb.sh /init-influxdb.sh
ENTRYPOINT ["/entrypoint.sh"]
CMD ["influxd"]
It might be possible that this is happening due to a silly mistake but I am not able to find where exactly is the problem.

Answer 1

So I was able to solve the problem by doing the following -
Changed the service name from web to kernel and in docker-compose.yml I added the command line for kernel service:
version: '3'
services:
mysqldb:
build:
context: ./sqldb
dockerfile: Dockerfilesqldb
container_name: sql
command: mysqld --user=root --verbose
# volumes:
# - ./sqldb:/app/sql
restart: always
# expose:
# - "3306"
ports:
- "3306:3306"
environment:
- MYSQL_ROOT_PASSWORD=secretpassword
- MYSQL_DATABASE=dbtest
- MYSQL_USER=user
- MYSQL_PASSWORD=password
- MYSQL_ALLOW_EMPTY_PASSWORD=yes
tsdbdb:
build:
context: ./tsdbdb
dockerfile: Dockerfiletsdb
container_name: influx
restart: always
# expose:
# - "8083"
# - "8086"
ports:
- "8083:8083"
- "8086:8086"
# volumes:
# - ./tsdb:/app/tsdb
env_file:
- './tsdbdb/influxdb.env'
grafana:
build:
context: ./grafana
dockerfile: Dockerfilegrafana
container_name: grafana
env_file:
- './grafana/grafana.env'
expose:
- "3000"
ports:
- "3003:3000"
links:
- tsdbdb
kernel:
build:
context: ./kernel
dockerfile: Dockerfilekernel
container_name: kernel
command: java -Djava.security.egd=file:/dev/./urandom -jar /app/kernel/app.war
restart: always
# expose:
# - "8080"
ports:
- "8082:8080"
links:
- tsdbdb
- mysqldb
# volumes:
# - ./kernel:/app/kernel
Although I am not sure why only adding command solved the problem.
