Build tags

DNS providers

Centauri by default supports a huge range of DNS providers thanks to the lego library it uses. This can, however, cause it to take a while to build and increase the size of the final binary.

If you know in advance you will only use a single DNS provider, you can use build tags to include only support for that provider in the binary. For example to support only the httpreq provider you can build with go build -tags lego_httpreq. See the legotapas project for more info.

Frontends

Similarly, if you know you only want to use the tcp or tailscale frontends, you can disable the other with the notcp or notailscale build tags.

Certificate stores

If you only want to use the default JSON certificate store, you can remove the Redis client from the binary with the noredis build tag. Attempting to use the redis certificate store in a binary built this way will result in an error at startup.
