Hi, @fahadahmadansari111 , thanks for the pr. A similar pr already exists here, please check #10. If there are any optimizations, welcome to submit again.

@Zepan This PR adds Docker support at +864 lines. However, PR #180 (goreleaser) was already merged and handles Docker builds. Additionally, PR #172 (Docker curl) was also merged.

Recommendation: Close. Docker support has been addressed by #180 and #172. This older PR likely conflicts with the current Docker setup.
