通過 jq 將 aws cli 解析為 CSV

Question

AWS CLI 輸出轉至 jq 以解析為 CSV。

這有效：

aws ec2 describe-network-acls |jq -r '.NetworkAcls[].Entries[] | [.RuleNumber, .Protocol, .Egress, .CidrBlock, .RuleAction] |@csv'

但這不會：

aws ec2 describe-network-acls |jq -r '.NetworkAcls[].VpcId + "," + .NetworkAcls[].NetworkAclId + "," .NetworkAcls[].Entries[] | [.RuleNumber, .Protocol, .Egress, .CidrBlock, .RuleAction]'

jq：錯誤（在：274）：無法用字符串“NetworkAcls”索引字符串

Answer 1

您必須小心使用[]進行迭代，以避免循環中的循環中的循環......

使用以下過濾器：

.NetworkAcls[]
| [.VpcId, .NetworkAclId]
 + (.Entries[] | [.RuleNumber, .Protocol, .Egress, .CidrBlock, .RuleAction])
| @csv

我得到：

"vpc-e68f6f8d","acl-b6d916dd",100,"-1",true,"0.0.0.0/0","allow"
"vpc-e68f6f8d","acl-b6d916dd",32767,"-1",true,"0.0.0.0/0","deny"
"vpc-e68f6f8d","acl-b6d916dd",100,"-1",false,"0.0.0.0/0","allow"
"vpc-e68f6f8d","acl-b6d916dd",32767,"-1",false,"0.0.0.0/0","deny"
