Tomcat folder

Here we are going to focus on the Tomcat server and Java services.

1. Go to /opt/zw-vmmc-docker/tomcat/conf and create log4j2.json config.json file:

   vim/opt/zw-vmmc-docker/tomcat/conf/log4j2.json

   And paste the next content:

   {
       "configuration": {
           "status": "warn",
           "name": "connectDWS",
           "packages": "psi.dws",
           "ThresholdFilter": {
               "level": "debug"
           },
           "appenders": {
               "Console": {
                   "name": "Console",
                   "PatternLayout": {
                       "pattern": "%d{HH:mm:ss.SSS} %-5level %X{request.id} %logger{36} - %msg%n"
                   }
               }
           },
           "loggers": {
               "root": {
                   "level": "warn",
                   "AppenderRef": {
                       "ref": "Console"
                   }
               }
           }
       }
   }

2. In the same folder create config.json file:

   vim /opt/zw-vmmc-docker/tomcat/conf/config.json

3. Copy the next lines on the file you are creating:

     {
     "tomcatLog4j2Config": "/usr/local/tomcat/conf/log4j2.json",
     "dws": {
       "kafkaBrokers": "kafka:9092",
       "urlsToEnqueueHighPriority": [],
       "urlsToEnqueueMediumPriority": [],
       "wsInternalDevVer": "0.0.19.02.02",
       "accessServerUsernameProfiler": "dwsUser",
       "accessServerPasswordProfiler": "dwsPass",
       "enqueueProgramFilter": [
         "pezQRuP6DE2"
       ],
       "gitDefaultUrlDefault": "http://localhost:8080/connectGitConfig/api/getConfig?type=ws_v2&ver=1",
       "gitDefaultUrlProd": "http://localhost:8080/connectGitConfig/api/getConfig?type=ws_v2&ver=1",
       "unsafeUrls": [
         "https://18.205.64.238/"
       ],
       "reqCustomHeaders": [
         {
           "key": "DWS-CONFIG",
           "urlRegex": "connectGitConfig/api",
           "value": "JBcLRzkItdEauNqqq91TQSjAREdzCZT2"
         },
         {
           "key": "DWS-SIGNATURE",
           "urlRegex": ".*",
           "value": "dws"
         }
       ],
       "initCachedGitConfigUrlsDefault": [],
       "initCachedGitConfigUrlsStage": [],
       "initCachedGitConfigUrlsTest": [],
       "initCachedGitConfigUrlsTrain": [],
       "initCachedGitConfigUrlsProd": [],
       "servicesAvailability": {
         "dhis2_available": "DHIS2",
         "legacy_available": "LEGACY",
         "mongo_available": "MONGO",
         "poeditor_available": "POEDITOR",
         "replica_available": "REPLICA"
       }
     },
     "routeNode": {
       "routeMap": {
         "mongoDB_Disabled": "3000",
         "cronWs": "http://localhost:3002",
         "webshot": "http://localhost:3005"
       }
     },
     "connectGitConfig": {
       "postgreSql": "localhost:5432"
     },
     "voucherGen": {
       "postgreSql": "localhost:5432",
       "mongoUrl": "mongo:3000"
     },
     "voucherGenWs": {
       "postgreSql": "localhost:5432",
       "mongoUrl": "mongo:3000"
     }
   }
   

4. After that, we will need to get the services. To get the resources you need to access to GitHub and download the war files of the next releases:

   • dws

   • connectTranslation

   • connnectGitConfig

   • connectVoucherGen

   • connectPWA // TODO: pending confirmation

   • Locator

5. All these war files have to be moved to /opt/zw-vmmc-docker/tomcat/webapps

6. The last step in the tomcat folder is to create the dockerfile in /opt/zw-vmmc-docker/tomcat :

   vim /opt/zw-vmmc-docker/tomcat/dockerfile

7. With the next content:

   # tomcat/Dockerfile
   
   # Use the Tomcat Docker Official Image
   FROM tomcat:9.0-jdk11-openjdk
   
   # Use root
   USER root
   
   WORKDIR /usr/local/tomcat
   
   # Not necessary, but, install vim and bash-completion
   RUN apt-get update 
   RUN apt-get install -y vim
   RUN apt-get install -y bash-completion 
   RUN  apt-get clean 
   RUN rm -rf /var/lib/apt/lists/* run 
   
   # Create 'tomcat' user
   RUN useradd -r -m -U -d /usr/local/tomcat -s /bin/false tomcat
   
   # Update repositories and install necessary tools:
   RUN apt-get update && apt-get install -y \
       passwd \
       && rm -rf /var/lib/apt/lists/*
   
   # Change user owner
   RUN chown -R tomcat:tomcat /usr/local/tomcat
   # Change to 'tomcat' user
   USER tomcat
   
   # Copy log4j2 config file
   COPY conf/log4j2.json /usr/local/tomcat/conf/
   
   # Copy config.json file
   COPY conf/config.json /usr/local/tomcat/conf/
   
   # Copy .war files to the tomcat webapps folder.
   COPY webapps/*.war /usr/local/tomcat/webapps/
   
   EXPOSE 8080
   
   # run Tomcat
   CMD ["catalina.sh", "run"]
