SERVER_ROLES =

$CAPISTRANO:HOSTROLES$ is a magic Capistrano placeholder that gets replaced with a comma-delimited list of roles *for each specific server individually*. See Capistrano::Command#replace_placeholders The awk command translates “app,web,db” into “role,role,role” to pass them to Chef

%Q{`echo '$CAPISTRANO:HOSTROLES$' | awk '{sub(/^/,"role["); sub(/$/,"]"); gsub(/,/,"],role["); print}'`}
