crane 安装出错——"crane:" is not a valid repository/tag

[conanca]

Expected behavior

安装成功

Actual behavior

安装过程报错
Building crane
ERROR: Error parsing reference: "crane:" is not a valid repository/tag

or

Building blackmamba
ERROR: Error parsing reference: "blackmamba:" is not a valid repository/tag

Information about the Issue

docker-compose 在build crane和blackmamba时，没有正确读出TAG这个环境变量。
尝试将deploy/docker-compose.yml的两处:${TAG}删掉，问题解决

Steps to reproduce the behavior

1. CentOS7，安装配置好docker相关软件
2. 下载解压crane。执行 CRANE_IP=172.18.24.69 ./bin/build-push-or-up.sh up
