Installation and Usage

• Download the reporsitory

  • git clone https://github.com/JeremyPSS/containers-microservices-mp.git

• Download Docker

  • For Windows you can download on the official website
  • For linux you can use a package manager

  sudo apt install docker.io docker-compose -y
  sudo systemctl start docker
  sudo usermod -aG docker $USER
  sudo systemctl restart docker

  Then Logout on your linux machine

• Run docker-compose up -d on your docker-compose.yml ubication

  • Also you can docker pull each image from my docker hub

• Open a browser and go to http://localhost:8080

• To restore the data

  • Go to http://localhost:8282
  • The creadentials are
    • password: root
    • username: root
    • server: db
    • database: system
  • On import select the file system.sql and click on execute

Considerations

• By default, the gateway only runs on port 8080 (this is the main port for the user)
• You can change the ports on each microservice, on /src/main/resources/application.yml or /src/main/resources/application.properties
  • To apply the changes you might run mvn package to generate the .jar or .war file again
    • Take in consideration the java version (check on each pom.xml)
• After running the containers, you can still use the API, you can verify using http://localhost:portMicroservice/api/nameMicroservice
  • Or in console you can test with curl [urlAPI] o
• You need to restore the database, you can do this with the adminer container
• To fetch the data with each microservice take time, so be patient
