Thanks for episode. Very usefull!

Awesome job

Good jobs

the problem in this approch is tha the IP address of a container can change when the container is stopped and started again, or if the host machine is restarted. so you should change the properties file everytime the ip is changed. i think using docker compse is the better approch

You're right!, Easy approach would be ... 'docker create network my-custom-network' and then running both the containers under '--network=my-custom-network'. Then, container IP will no longer be needed.

Problem: You cannot create a .jar after you change localhost to different value. Solution 2: You can activate Toggle 'Skip Tests' mode in Maven Tab before creating jar. (looks like circle, like this (/)) Solution 1: You should clean your maven project in common way, after that you should go to the terminal in intelliJ(i hope you use intelliJ, cause idk if it works in other IDE's). In terminal you should write next: mvn install -DskipTests=true and press CTRL+ENTER, if you press only enter it will not work. If this comment helped you just press the like button. P.S. IDK why the author avoid answer to this question, i read all his answers down below and that is just "ahh, yeah, you can't do this" without solution :/ P.P.S. If you try to use this command in terminal but it's not work and you just skipped the section above use ctrl+enter, it's might be a little bit confusing like it was for me)

At the beginning of your pom.xml where the groupId, artifact id, version etc.. are defined. Right below that you should have xml tag called jar. Secondly there should also be a pluging configured called maven-jar-plugin. But these things are by default configured when you freshly create a spring boot app. Anyways, give it a try.

Suspecting:: Hope your are giving ipv4(you can get it by runnung 'docker inspect containerId' as shown in the video) instead of localhost. If you've changed the port of postgres then obviously you have to give the correct one. Also suspecting:: Make sure all the connection properties are correct incase if you're getting it from env variable.

After changing localhost to IpAddress in spring.datasource.url, I can't start the application directly from Intellij. Therefore, I can't run "mvn clean install" properly. Is that ok or am I doing something wrong? Is the whole point of Dockerfile not to run application from Intellij interface, rather running it everytime using the Dockerfile?

@CodeVice111

Жыл бұрын

If you have already dockerized the postgres, but not yet dockerized the spring boot app... then you should use localhost instead of iPaddress in the db url. Ip address will only help you connecting to dockerized postgres when the spring boot app is also dockerized. 👌 thanks for watch.

If you are only running postgres on docker container, but not spring boot app. Then connecting to postgres db is quite simple. It should be through : localhost 5432 spring.datasource.url=jdbc:postgresql://localhost:5432/my-db spring.datasource.username=give_username spring.datasource.password=give-password Additionally u hv to specify spring.jpa.hibernate.ddl-auto=update spring.jpa.show-sql=true spring.jpa.properties.hibernate.format_sql=true spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL81Dialect

Understood. When both apps hv their own container, then they hv be in the same network. Here is how: docker network create myNetwork Now u can include the netwoek using --net flag in the run cmd. Example: docker run -d -p 8000:8000 --net myNetwork --name springboot-container springboot-image docker run -d -p 5432:5432 --net myNetwork --name postgres-container postgres Try this out.
