Docker ve Wildfly

Örnek - Kullanmayın
Kullanmayın çünkü "jboss/wildfly" artık "quay.io" olarak değişti. Şöyle yaparız
FROM jboss/wildfly
ADD my-app.war /opt/jboss/wildfly/standalone/deployments/
ve şöyle yaparız
docker build --tag=my-app . && docker run -it my-app
Örnek - quay.io 
Şöyle yaparız. -b ile bind seçenekleri belirtiliyor.
FROM quay.io/wildfly/wildfly:26.0.0.Final
COPY my-standalone.xml /opt/jboss/wildfly/standalone/configuration/
#Deploy
COPY ./target/*.war /opt/jboss/wildfly/standalone/deployments/

# Run with custom configuration
CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0",
  "-c","my-standalone.xml"]
Bu image için kullanılan DockerFile GitHub'da burada. Burada FROM jboss/base-jdk:11 görülebilir.
jboss/base-jdk:11 için kullanılan DockerFile GitHub'da burada. FROM jboss/base:latest görülebilir
jboss/base için kullanılan DockerFile GitHub'da burada. FROM centos:7 görülebilir

Örnek -  quay.io  + runtime
Şöyle yaparız
FROM quay.io/wildfly/wildfly-runtime-jdk11
COPY --chown=jboss:root target/server $JBOSS_HOME
RUN chmod -R ug+rwX $JBOSS_HOME
Örnek - Admin Kullanıcısı
Şöyle yaparız
FROM quay.io/wildfly/wildfly
#Create user
RUN /opt/jboss/wildfly/bin/add-user.sh admin Admin#70365 --silent

CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]
Örnek - Olmayan bir Wildfly Sürümünü İndir ve JDK Kur
Şöyle yaparız. Burada JDK 17 de kuruluyor
#Bring centos

# Create a user and group used to launch processes
# The user ID 1000 is the default for the first "regular" user on Fedora/RHEL,

RUN groupadd -r jboss -g 1000 && useradd -u 1000 -r -g jboss -m -d /opt/jboss -s /sbin/nologin -c "JBoss user" jboss && \

#Deploy
ADD  modules/system/layers/base/com /opt/jboss/wildfly/modules/system/layers/base/com/
COPY standalone-full.xml /opt/jboss/wildfly/standalone/configuration
COPY ./build/libs/rwGuiEar.ear /opt/jboss/wildfly/standalone/deployments/

#Create user

CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0", "-c","standalone-full.xml"]
Eğer deploy işlemini bir artifactory sunucusundan yapıyorsak şöyle yaparız
...

USER root
RUN curl http://artifactory.foo.com/artifactory/release-local/mysql-connector-java-8.0.17.jar > /opt/jboss/wildfly/modules/system/layers/base/com/mysql/main/mysql-connector-java-8.0.17.jar

USER jboss
COPY files/standalone-full.xml /opt/jboss/wildfly/standalone/configuration
RUN curl http://artifactory.foo.com/release/rwGuiEar.ear > /opt/jboss/wildfly/standalone/deployments/rwGuiEar.ear

...
Çalıştırmak için şöyle yaparız. Burada yerelde çalışan vitesstestserver isimli container, wildfly25 ile aynı ağa alınıyor
# Create a network
docker network create myNetwork

# build image
docker build -t wildfly25 .
docker run -d --rm --network myNetwork --name wildfly25
  -p 8080:8080 -p 9990:9990 wildfly25

# Connect a running container to a network
docker network connect myNetwork vitesstestserver
veya vitesstestserver'ı başlatırken ağa almak için şöyle yaparız
docker build -t vitesstestserver .
docker run --rm --name vitesstestserver --network myNetwork
  -p 33577:33577 vitesstestserver
Bağlanmak için şöyle yaparız
http://localhost:8080/rwgui/
Örnek - /usr/sbin/sshd kullanan Redhat/ubi8
Burada wildfly + ssh kuruluyor. Şöyle yaparız

Örnek 
4 tane ubi image var.
micro, minimal, standard, ve init.

micro için açıklama şöyle
The ubi-micro is the smallest possible UBI image, obtained by excluding a package manager and all of its dependencies which are normally included in a container image. This minimizes the attack surface of container images based on the ubi-micro image and is suitable for minimal applications, even if you use UBI Standard, Minimal, or Init for other applications. The container image without the Linux distribution packaging is called a Distroless container image.
Açıklaması şöyle
In the following Dockerfile, we utilize the ubi-init (multi-service) image, which supports systemd and has the CMD /sbin/init as the default to start the systemd init service. 
Şöyle yaparız
