솔직히 도커는 고래이미지가 더 귀엽지 않나...쩝

[Docker] wildfly Dockerfile을 이용한 Container 생성 (+Admin)

 

docker로 작업할 때 가장 효율이 나는 것들 중 하나는 바로 웹서버이다.

nginx 띄우는 예제는 많지만 wildfly를 더 많이 사용해왔기 때문에 wildfly container를 만들어 띄워보는 것을 해보겠다.

 

1. Host OS 방화벽 설정

#새로운 포트 개방
[minggu92@cloud dockerfiles]$ firewall-cmd --add-port=1003/tcp --permanent
SUCCESS!
[minggu92@cloud dockerfiles]$ firewall-cmd --reload

 

2. wildfly에서 제공하는 Dockerfile

# Use latest jboss/base-jdk:11 image as the base
FROM jboss/base-jdk:11

# Set the WILDFLY_VERSION env variable
ENV WILDFLY_VERSION 26.0.1.Final
ENV WILDFLY_SHA1 08908faf9ae99e5fb6374979afbffea461aadc2c
ENV JBOSS_HOME /opt/jboss/wildfly

USER root

# Add the WildFly distribution to /opt, and make wildfly the owner of the extracted tar content
# Make sure the distribution is available from a well-known place
RUN cd $HOME \
    && curl -L -O https://github.com/wildfly/wildfly/releases/download/$WILDFLY_VERSION/wildfly-$WILDFLY_VERSION.tar.gz \
    && sha1sum wildfly-$WILDFLY_VERSION.tar.gz | grep $WILDFLY_SHA1 \
    && tar xf wildfly-$WILDFLY_VERSION.tar.gz \
    && mv $HOME/wildfly-$WILDFLY_VERSION $JBOSS_HOME \
    && rm wildfly-$WILDFLY_VERSION.tar.gz \
    && chown -R jboss:0 ${JBOSS_HOME} \
    && chmod -R g+rw ${JBOSS_HOME}

# Ensure signals are forwarded to the JVM process correctly for graceful shutdown
ENV LAUNCH_JBOSS_IN_BACKGROUND true

USER jboss

# Expose the ports in which we're interested
EXPOSE 8080

# Set the default command to run on boot
# This will boot WildFly in standalone mode and bind to all interfaces
CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0"]

 

3. docker build

#docker build -t [name]:[tag] [경로] -f [*.Dockerfile] 
[minggu92@cloud dockerfiles]$ docker build -t wildfly:0.1 /dockerfiles/ -f /dockerfiles/wildfly.Dockerfile

5. 확인

일단 서버가 기동 되는 것을 확인, 이제 상황에 맞게 커스터마이징 하면 된다.

 

6. Custormizing

# Use latest jboss/base-jdk:8 image as the base
FROM jboss/base-jdk:8

#metadata

ENV JBOSS_HOME /opt/jboss/wildfly

USER root

# Add the WildFly distribution to /opt, and make wildfly the owner of the extracted tar content

RUN cd $HOME \
    && curl -L -O https://github.com/wildfly/wildfly/releases/download/$WILDFLY_VERSION/wildfly-$WILDFLY_VERSION.tar.gz \

# Change resources

# Add wildfly admin account

RUN /opt/jboss/wildfly/bin/add-user.sh -u admin -p minggu #admin --silent

# Make volume directory

#VOLUME ${JBOSS_HOME}/standalone/deployments

# Ensure signals are forwarded to the JVM process correctly for graceful shutdown
ENV LAUNCH_JBOSS_IN_BACKGROUND true

# Expose the ports in which we're interested
EXPOSE 8080 9990

# Set the default command to run on boot
# This will boot WildFly in standalone mode and bind to all interfaces
CMD /opt/jboss/wildfly/bin/standalone.sh -c standalone.xml -b 0.0.0.0 -bmanagement 0.0.0.0 --debug
#CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0"]

미리 module을 정의한 standalone.xml을 준비해서 실행하면 된다

 

팁! ADD 로 war 경로를 설정했지만 volume으로 선언하면 war가 add되지 않는다.

volume설정된 폴더로 war를 옮겨주자

 

Admin 페이지도 성공!
