CircleCI Docker构建未通过传递环境变量

Question

我正在使用ecr orb构建并将映像推送到注册表，但是由于某些原因，circle env var在构建过程中不可用。

这是我的config.yml

（我已注释掉一些故障排除步骤）

      #             ELB_ARN=$(aws elbv2 describe-target-groups --target-group-arns $TARGET_GROUP_ARN | jq -r '.TargetGroups[0].LoadBalancerArns[0]')
      #             ELB_DNS_NAME=$(aws elbv2 describe-load-balancers --load-balancer-arns $ELB_ARN | jq -r '.LoadBalancers[0].DNSName')

我对Orbs上下文/ circleci的环境变量不了解什么？

谢谢大家！
