ymc-github / docker-ltmj

deploy ltmj(Linux+tomcat+mysql+java) using docker

background

to standard and simple building and running java web in dev/pro env.

dependences

some important soflt need to be prepared:

• Git
• Docker
• Docker-Compose

database for mysql

• hostname: mysql

the state will add a host resovle in the db cm mysql, in file /etc/hosts with content xxx.xx.xx.xx mysql. it will map the address http://mysql to the db cm mysql,equals to http://localhost in the db cm mysql

data for persistence

the data in cm will destory when the cm is destory, you need to make volume maping from cm path to your pm path in docker-compose.yml:

• /var/lib/mysql the db cm mysql data file path must to mount to your pm path
• /usr/local/tomcat/logs the serve cm tomcat log file path .you can mount to your pm path too
• /data the db cm redis data file path
• /data/activemq the db cm activemq data file path will map the address http://mysql to the db cm mysql,equals to http://localhost in the db cm mysql

project simple usage

after debuging the project,start with -d arg to run in backgroud process. you also can use docker-compose logs -f to get start log.

# run in backgroud process
docker-compose up -d

# get the start log
docker-compose logs -f

some important solft for java web

• JAVA ：1.8
• Tomcat ：8.5.41
• maven ：maven:3.6.1-jdk-8
• MySQL ：10.3.15
• Redis ：5.0.7
• ActiveMQ ：5.14.3

the maven you can update it in init-conf.sh file. the other solft version updated in docker-compose.yml file or Dockerfile file

# fetch from a remote image
# image: redis:5.0.7
# build image with a local config
  build: ./redis

after updating docker-compose.yml file or Dockerfile file,need to rebuild image .you can run as below but not last:

docker-compose up --build

find some thing:

#find factor for:Bind for 0.0.0.0:8080 failed: port is already allocated'
ps -aux | grep -v grep | grep docker-proxy
#> 172.20.1.2 -container-port 8080

#reason: nginx uses 8080:80 and tomcat uses 8080:8080

how to solve:

#update docker-compose.yml ports for nginx and tomcat serve
