custom_documenter_deployment.jl

#=
The following works with Documenter.jl 0.24. 

There seems to be a breaking change in Documenter.jl 0.25 to return 
something different from the `deploy_folder` function.
=#

struct MyDeployConfig <: Documenter.DeployConfig
end

Documenter.deploy_folder(cfg::MyDeployConfig;
                         repo, devbranch, push_preview, devurl, kwargs...) = devurl

Documenter.authentication_method(::MyDeployConfig) = Documenter.SSH

deploydocs(
    repo = "github.com:<user>/<repo>.git",
    deploy_config = MyDeployConfig()
)
