部署教程 | 使用Docker部署WeBASE-Front服务¶

1、配置镜像源¶

创建或修改 /etc/docker/daemon.json 文件，内容如下：

{
    "registry-mirrors": [
        "http://hub-mirror.c.163.com",
        "https://docker.mirrors.ustc.edu.cn",
        "https://registry.docker-cn.com"
    ]
}

重启docker服务：

service docker restart

2、拉取webase-front镜像¶

拉取命令：

docker pull webasepro/webase-front

执行结果：

Using default tag: latest
latest: Pulling from webasepro/webase-front
25fa05cd42bd: Pull complete 
a67ba6b28d8a: Pull complete

Status: Downloaded newer image for webasepro/webase-front:latest
docker.io/webasepro/webase-front:latest

查看拉取的镜像：

docker images

REPOSITORY                                                  TAG       IMAGE ID       CREATED         SIZE
webasepro/webase-front                                      latest    a2d3effc01d9   12 months ago   610MB

3、运行镜像¶

执行命令：

docker run -d --name WeBASE-Front -v /docker_file/front/dist/log/:/dist/log -p 5002:5002 webasepro/webase-front:latest

查看容器状态：

docker ps -a

CONTAINER ID   IMAGE                           COMMAND                  CREATED          STATUS                      PORTS                                       NAMES
da20cddd5379   webasepro/webase-front:latest   "/bin/sh -c 'cp -r /…"   15 seconds ago   Exited (1) 14 seconds ago                                               WeBASE-Front

未启动成功，查看日志：

docker logs da20cddd5379

报以下错误：

cp: cannot stat '/dist/sdk/*': No such file or directory

4、自己构建镜像¶

（1）、编译代码修改配置¶

按照交易部署说明（链接https://webasedoc.readthedocs.io/zh_CN/latest/docs/WeBASE-Front/install.html）完成到第4步，主要需要修改的是“//连接节点的监听ip” 和 “//配置所连节点的绝对路径，用于监控节点配置与日志” 这两个配置，确保地址正确和可连接。

（2）、修改Dockerfile文件¶

进入到WeBASE-Front\docker\build目录，修改Dockerfile文件，修改后内容如下：

FROM java:8

COPY gradle                /dist/gradle
COPY static                /dist/static
COPY lib                  /dist/lib
COPY conf                 /dist/conf
COPY apps                 /dist/apps
COPY sdk                  /dist/sdk

WORKDIR /dist
EXPOSE 5002

ENV CLASSPATH "/dist/conf/:/dist/apps/*:/dist/lib/*"

ENV JAVA_OPTS " -server -Dfile.encoding=UTF-8 -Xmx512m -Xms512m -Xmn256m -Xss512k -XX:MetaspaceSize=256m -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/log/heap_error.log  -XX:+UseG1GC -XX:MaxGCPauseMillis=200 "
ENV APP_MAIN "com.webank.webase.front.Application"

# start commond
ENTRYPOINT   java ${JAVA_OPTS} -Djdk.tls.namedGroups="secp256k1", -Duser.timezone="Asia/Shanghai" -Djava.security.egd=file:/dev/./urandom, -Djava.library.path=/dist/conf -cp ${CLASSPATH}  ${APP_MAIN}

（3）、创建镜像¶

复制Dockerfile文件到编译后生成的dist目录中，执行创建命令：（注意最后有个点）

docker build -f Dockerfile -t webase-front:myself .

执行结果：

docker run -d --name WeBASE-Front -v /docker_file/front/dist/log/:/dist/log -p 5002:5002 webase-front:myself

查看运行的容器：

docker ps
