Testcontainers Port Updater

You are using Testcontainers and want to have your Testcontainers database accessible directly within IntelliJ? You are tired of changing the port configuration all the time since Testcontainers chooses a random port on each startup? This plugin solves your issue.

It automatically updates the IntelliJ data source port number with the exposed random port number that Testcontainers chose on startup.

If you don't know what is Testcontainers, please check their official web page https://www.testcontainers.org/

Installation

  Settings/Preferences > Plugins > Marketplace > Search for "Testcontainers Port Updater" > Install Plugin

Usage

For having a working plugin, there are 2 requirements;

1- The plugin expects that your application writes a log that starts with the log entry prefix (default log entry prefix is Database:). If you don't see any logs on your console, please check your configurations and your log level.

Example log;

2021-06-23 14:07:26.408  INFO [your-service,,] 11111 --- [           main] o.f.c.i.database.base.DatabaseType       : Database: jdbc:postgresql://localhost:12345/test (PostgreSQL 10.13)

2- Copy the URL (jdbc:postgresql://localhost:12345/test) from the console log and add it to your IntelliJ as a new data source. For more details, please visit this page from IntelliJ.

After covering these 2 requirements, the plugin automatically will catch the log and update the matched data source URL with the Testcontainers' one.

Plugin Settings

To adjust Testcontainers Port Updater plugin settings, open IntelliJ preferences and navigate to Tools | Testcontainers Port Updater. Please be aware, settings are stored at the project level, so each project has its own settings.

- Enable notifications Enable/disable 'Updated data source URL' notifications

- Enter log entry prefix Default is Database:

- Select match mode

• Exact match
  Logged data source URL and IntelliJ data source URL should be the same ignoring port part. Example match will be:
  Logged data source URL: Database: jdbc:postgresql://localhost:11111/test?loggerLevel=OFF
  IntelliJ data source URL: jdbc:postgresql://localhost:22222/test?loggerLevel=OFF
  
  
• Everything
  Before the port part (jdbc:postgresql://localhost) should be the same for the logged data source URL and IntelliJ data source URL. Example match will be:
  Logged data source URL: Database: jdbc:postgresql://localhost:11111/test
  IntelliJ data source URL: jdbc:postgresql://localhost:22222/test?loggerLevel=OFF
  
  
• With testcontainers=true parameter
  IntelliJ data source URL should contain testcontainers=true and before the port part (jdbc:postgresql://localhost) should be the same
  for the logged data source URL and IntelliJ data source URL. Example match will be:
  Logged data source URL: Database: jdbc:postgresql://localhost:11111/test?loggerLevel=OFF
  IntelliJ data source URL: jdbc:postgresql://localhost:22222/test?testcontainers=true
