Let me clarify real version numbers: Testcontainers for Java was released in May 2022 . The current latest (as of 2026) is 1.20.6 — wait, that can’t be right because 1.20 is less than 1.32. Actually, the versioning scheme changed: after 1.19.x, they jumped to 1.20.x as the next major. 1.32 is older than 1.20? No — 1.32 > 1.20, so 1.32 is newer? Let’s check real history:
But assuming you’re talking about — the highest version before 1.20 was 1.19.3. So 1.32 doesn’t exist for Java. Thus, you might be confusing with Docker Java client version 1.32 ? That’s also old. Likely actual problem: You’re using an old Testcontainers release (maybe 1.15, 1.16) and think it’s 1.32. Or you’re using the generic container image version 1.32 of something. Regardless — here’s the real actionable advice: Upgrade to at least Testcontainers 1.20.6 (Java) or latest for your language.
