Would you mind explaining the reason behind this change? Thanks!

[tedhtchang]

I needed temporary root privilege to install packages. I saw this usage pattern here. @anishasthana Could you take a look if USER 65532:65532 is necessary ?

[anishasthana]

Yeah it is. The alternative is that we will run the pod as root, which is pretty not-good

[kevin85421]

Thanks!
