List public IP addresses of EC2 instances
提问by Bas Peeters
I want to list the public IP addresses of my EC2 instances using Bash, separated by a delimiter (space or a new-line).
我想使用 Bash 列出我的 EC2 实例的公共 IP 地址，用分隔符（空格或换行符）分隔。
I tried to pipe the output to jqwith aws ec2 describe-instances | jq, but can't seem to isolate just the IP addresses.
我试图管道输出到JQ有aws ec2 describe-instances | jq，但似乎不能只是孤立的IP地址。
Can this be done by awsalone, specifying arguments to jq, or something else entirely?
这可以aws单独完成，为 指定参数jq，还是完全其他的东西？

- Filter on running instances (you can drop that part if you don't need it)
- Query for each PublicIPaddress and the Name Tag, handling when Name isn't set
- 过滤正在运行的实例（如果不需要，可以删除该部分）
- 查询每个 PublicIPaddress 和 Name Tag，在未设置 Name 时处理
aws ec2 describe-instances \
--filter "Name=instance-state-name,Values=running" \
--query "Reservations[*].Instances[*].[PublicIpAddress, Tags[?Key=='Name'].Value|[0]]" \
--output text

The below command would list the IP addresses of all your running EC2 instances
以下命令将列出所有正在运行的 EC2 实例的 IP 地址
aws ec2 describe-instances | grep PublicIpAddress | grep -o -P "\d+\.\d+\.\d+\.\d+" | grep -v '^10\.'
Hope that answers your query...
希望能解答您的疑问...
But this works without all the errors about access:
但这可以在没有关于访问的所有错误的情况下工作：
wget -qO- http://instance-data/latest/meta-data/public-ipv4/|grep .

You can use instance metadataso you can run the following command from the ec2 instance:
您可以使用实例元数据，以便从 ec2 实例运行以下命令：
curl http://169.254.169.254/latest/meta-data/public-ipv4
and it will give you the public IP of the instance. If you want the private IP, you will run
它将为您提供实例的公共 IP。如果你想要私有IP，你将运行
curl http://169.254.169.254/latest/meta-data/local-ipv4
