MinIO Containers

Testcontainers can be used to automatically instantiate and manage MinIO containers.

Usage example

Create a MinIOContainer to use it in your tests:

Starting a MinIO container

MinIOContainer container = new MinIOContainer("minio/minio:RELEASE.2023-09-04T19-57-37Z");

The MinIO Java client can be configured with the container as such:

Configuring a MinIO client

MinioClient minioClient = MinioClient
    .builder()
    .endpoint(container.getS3URL())
    .credentials(container.getUserName(), container.getPassword())
    .build();

If needed the username and password can be overridden as such:

Overriding a MinIO container

MinIOContainer container = new MinIOContainer("minio/minio:RELEASE.2023-09-04T19-57-37Z")
    .withUserName("testuser")
    .withPassword("testpassword");
