Where to get Docker Certification to upskill my career?

Docker community,

I’m currently aiming to enhance my skills by delving into Docker. Having been with an IT company for the past 1.5 years, I’m eager to elevate my expertise. However, a recurring challenge I encounter during interviews is the requirement for Docker certification. I’m seeking recommendations for the best Docker certification program that offers updated content and accreditation. Any suggestions or assistance would be greatly appreciated.
