template

deploy dir is template file,the file suffix is yaml.tmpl or yml.tmpl . need replace env. the files name auto rename to .yaml/.yml. the support env prefix: TEMPLATE_

command template

 drone-kube template  --deploy=xxx  

use docker template

 docker run -ti --network=host -e TEMPLATE_IMAGES1=alpine   cuisongliu/drone-kube bash 
 drone-kube template --deploy=xxx
