@wonderflow I've updated postgres addon, I hope now you will be able to run Bytebase with postgres addon :)

[wonderflow]

can we reuse the expose trait?

[MdSahil-oss]

@wonderflow I've updated postgres-expose trait as expose trait. Please reivew it again.

[wonderflow]

why do we need to create a new one instead of using expose trait?

[wonderflow]

Generally LGTM

I had the same concern with @wonderflow . It seems that the existing Expose trait can accomplish the same functionality. Have you considered using it instead

@wangyikewxgm @wonderflow I tried to do so, But I'm getting an error

could not create cluster: could not create master endpoint: endpoints "postgres" already exists

it seems like expose trait is getting created first then postgres cluster using built in expose trait.

@MdSahil-oss Hi, does this addon work? We can use postres-expose trait you added instead of built-in expose trait.
