Hello Team,

Can we use custom image and promote it in Convox?

I don’t want to use `convox build` command and want to do a normal docker build.

And the custom build image I want to use at the time of promotion.

Is this possible?

Because currently I saw that when we run `convox build` it associates a specific Release Id and Build Id to an image and then we have to provide the release id at the time of promotion.

Just wanted to check the feasibility?

Hey, if you’ve built your image outside of Convox you can specify to use that image in your `convox.yml`.

Just try something like:

```auto
services:
  web:
    image: imagename

```

Also, see the docs section on adding [private registries](https://docs.convox.com/deployment/private-registries) if that’s where you are storing your image…
