如何在docker环境下用Mysql启动Aerogear统一推送服务器

Question

我正在努力在一个有mysql数据库的docker环境中启动一个aerogear统一推送服务器。我在跟着Aerogear documentation here走。

所以我启动了一个mysql docker容器。

docker run --name aerogearsql -e MYSQL_ROOT_PASSWORD=sqlpwd -d mysql

我在其上应用了在aerogear文档中所说的内容。

docker exec -ti aerogearsql -u root -p
mysql> create database unifiedpush default character set = "UTF8" default collate = "utf8_general_ci";
mysql> create user 'unifiedpush'@'localhost' identified by 'unifiedpush';
mysql> GRANT SELECT,INSERT,UPDATE,ALTER,DELETE,CREATE,DROP ON unifiedpush.* TO 'unifiedpush'@'localhost';

然后，我已经使用以下docker文件准备了一个docker图像，并应用了aerogear文档中的内容。这是docker文件

FROM jboss/wildfly
MAINTAINER yves.nicolas@dynamease.com


ENV AEROGEAR_VERSION 1.0.3
ENV AEROGEAR_FILES /usr/local/share/aerogear
ENV AEROGEAR_DIR $AEROGEAR_FILES/aerogear-unifiedpush-server-$AEROGEAR_VERSION
ENV JBOSS_HOME /opt/jboss/wildfly


# Run everything below as root user
USER root

# Set the Java environment variable
ENV JAVA_HOME /usr/lib/jvm/java-1.7.0-openjdk

RUN mkdir -p $AEROGEAR_FILES && chmod -R ugo+rwx $AEROGEAR_FILES

# Install Maven it will be needed for my SQL
RUN curl -L -o /etc/yum.repos.d/epel-apache-maven.repo http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo \
    && yum -y install apache-maven && yum clean all

# Switch back to jboss user
USER jboss


# Get Aerogear version
WORKDIR $AEROGEAR_FILES

RUN curl -L -o aerogear-unifiedpush-server-$AEROGEAR_VERSION-dist.tar.gz https://github.com/aerogear/aerogear-unifiedpush-server/releases/download/$AEROGEAR_VERSION/aerogear-unifiedpush-server

    && tar -xvf aerogear-unifiedpush-server-$AEROGEAR_VERSION-dist.tar.gz  \
    && cp -r aerogear-unifiedpush-server-$AEROGEAR_VERSION/databases/src/main/resources/modules/com $JBOSS_HOME/modules/


# Do Sql Dependency maven
RUN mvn dependency:copy -Dartifact=mysql:mysql-connector-java:5.1.18 -DoutputDirectory=$JBOSS_HOME/modules/com/mysql/jdbc/main/

# can remove maven at this stage
USER root
RUN yum -y erase apache-maven && yum clean all

# Switch back to jboss user
USER jboss


WORKDIR $JBOSS_HOME

VOLUME $JBOSS_HOME

EXPOSE 8443

CMD ["/opt/jboss/wildfly/bin/standalone.sh","-b","0.0.0.0"]

从这个映像中，我启动了一个链接到mysql的容器

docker run  --name essaipush --link aerogearsql:mysql -v /home/yves:/host -p 8443:8443 yvnicolas/aerogear

Wildfly服务器在使用docker exec还没有部署的情况下启动得很好，然后我应用了mysql cli脚本。

$ ./path/to/SERVER_HOME/bin/jboss-cli.sh --file=/path/to/mysql-database-config-wildfly.cli

在我将mysql- database -config-wildfly.cli更新为使用mysql而不是localhost作为数据库访问主机之后。

仍然使用docker exec，我最终将两个war文件移动到standalone/deployment目录中，但这并不顺利，因为它似乎找不到数据库。

以下是所引发的异常的一些副本。由于我不熟悉Hibernate和Jboss，我不知道根本原因是这个hibernate.dialect没有设置，还是两个容器之间的通信问题。

我们现在有了docker-compose yml文件(适用于1.1.0) https://github.com/aerogear/aerogear-unifiedpush-server/tree/master/databases/docker

在此基础上添加一些文档：https://staging.aerogear.org/docs/unifiedpush/ups_userguide/index/#Docker-databases
