step "1. Archiving application directory"

tar -zcvf ${RELEASE_LOCAL} -C ${APP_DIR} .



step "2. Uploading archive"

ssh -i ${SERVER_KEY} ${SERVER} <<- SSHCOMMANDS
  mkdir -p ${RELEASE_ARCHIVES}
SSHCOMMANDS

scp -i ${SERVER_KEY} ${RELEASE_LOCAL} "${SERVER}:${RELEASE_ARCHIVE}"



step "3. Extracting archive and building new release"

ssh -i ${SERVER_KEY} ${SERVER} <<- SSHCOMMANDS
  mkdir -p ${RELEASE_PATH}
  tar -xvf ${RELEASE_ARCHIVE} -C ${RELEASE_PATH}
  rm -rf ${RELEASE_CURRENT}
  ln -s ${RELEASE_PATH} ${RELEASE_CURRENT}
