### Available image tags ### Available image tags
This image has been built on CentOS 7 since its inception, but the new CentOS 8 does [not include supervisor](https://github.com/juanluisbaptiste/docker-postfix/issues/16) anymore, so I have started migrating this image to Alpine linux. So currently there are two image tags available: Currently we only handle a rolling release of new versions so only _latest_ tag is available, but there is [work in progress](https://github.com/juanluisbaptiste/docker-postfix/pull/29) to start releasing versioned images to be able to pin to specific versions in production deployments.
* juanluisbaptiste/postfix:latest, current CentOS 7 based image *_NOTES_*:
* juanluisbaptiste/postfix:alpine, new Alpine based image * The _alpine_ tag has been switched to use the master branch, but it's irrelevant as it is the same as _latest_.
* Old CentOS 7 based image is avaiable on the _centos_base_image branch_, but it is not being developed any more.
If testing goes well for some time, then the current CentOS image will be replaced by the new Alpine one, and _latest_ tag will point to it.
