How to Optimize Git-Actions (like caching run on MySQL container)

[junha-ahn]

Hi I wonder How to optimize my git-actions like caching or etc...

When I didn't change my production code / test code (in src/...)

It runs during 2 min. I think It doesn't use any caching

so I want to optimize my Integration CI on git actions

• At least, How to caching run MySQL container (I think I never changed image tag - or change only table structure)

Is there any official guide or best practice? (git-actions with java/jvm)
and plz give me a available Slack link!

  integrationTest:
    runs-on: ubuntu-latest
    needs: set-up
    if: always()
    steps:
      - uses: actions/checkout@v3
      - name: Set up JDK 17
        uses: actions/setup-java@v3
        with:
          java-version: '17'
          distribution: 'temurin'

      - name: integrationTest
        uses: gradle/gradle-build-action@749f47bda3e44aa060e82d7b3ef7e40d953bd629
        if: always()
        with:
          arguments: integrationTest

from git actions file

dependencies {
    ...
    integrationTestImplementation("org.springframework.boot:spring-boot-testcontainers")
    integrationTestImplementation("org.testcontainers:junit-jupiter")
    integrationTestImplementation("org.testcontainers:mysql")
}

from build.gradle.kts

@SpringBootTest
@Testcontainers
abstract class AbstractIntegrationTest {

    companion object {
        val mysqlContainer = MySQLContainer("mysql:8.0.33")
            .withConfigurationOverride("./db/mysql/conf.d")

        @JvmStatic
        @DynamicPropertySource
        fun datasourceConfig(registry: DynamicPropertyRegistry) {
            mysqlContainer.start()
            registry.add("spring.datasource.url", mysqlContainer::getJdbcUrl)
            registry.add("spring.datasource.username", mysqlContainer::getUsername)
            registry.add("spring.datasource.password", mysqlContainer::getPassword)
        }
    }
}

AbstractIntegrationTest.kt in integrationTest folder

• use mysql container
