Httpd service not starting in Alpine container

Hello,

Trying to run both java and http service in a single Alpine image, somehow httpd service not starting

below is the dockerfile used

FROM java:8-jdk-alpine
RUN apk add --no-cache apache2-proxy apache2-ssl apache2-utils

WORKDIR /var/www/
COPY html/ .

WORKDIR /var/backed
COPY backed-0.0.1-SNAPSHOT.jar .

EXPOSE 80/tcp
EXPOSE 8085/tcp

CMD [“sh”,"-c","/usr/sbin/httpd -D FOREGROUND && java -jar /var/backed/backed-0.0.1-SNAPSHOT.jar"]

Docker run command:
sudo docker run -p 8080:80 -p 8085:8085 server:1.0

AH00558: httpd: Could not reliably determine the server’s fully qualified domain name, using 172.17.0.2. Set the ‘ServerName’ directive globally to suppress this message

Posted snipped of the container run above, I think the httpd service quits immediately.

I could able to view jhipster home page on 172.17.0.2:8085, but frontend 172.17.0.2:8080 or 172.17.0.2 is connection timed out.

How can make the front end work?

Thanks,

With the syntax command1 && command2, command2 is run only when command1 is done and successfully. That’s probably not what you meant with that CMD line in your Dockerfile.
You’ll need to write a script for that.

What happen is : apache fail, then your java app is started. Here is the only message apache says :

AH00558: httpd: Could not reliably determine the server’s fully qualified domain name, using 172.17.0.2. Set the ‘ServerName’ directive globally to suppress this message

You might want to fix it’s configuration.

But IMHO, you should use distinct containers for each services, which mean 1 container for your java app and one for apache (then you could even just use the httpd:alpine and overwrite it’s configuration file with a docker config create .... config.). All you have to do is to write a simple docker-compose.yaml file :wink:
