List public IP addresses of EC2 instances
Solution 1:
Directly from the aws cli:
aws ec2 describe-instances \
--query "Reservations[*].Instances[*].PublicIpAddress" \
--output=text
Solution 2:
- 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
aws ec2 describe-instances \
--filter "Name=instance-state-name,Values=running" \
--query "Reservations[*].Instances[*].[PublicIpAddress, Tags[?Key=='Name'].Value|[0]]" \
--output text
Solution 3:
The below command would list the IP addresses of all your running EC2 instances
aws ec2 describe-instances | grep PublicIpAddress | grep -o -P "\d+\.\d+\.\d+\.\d+" | grep -v '^10\.'
Hope that answers your query...
But this works without all the errors about access:
wget -qO- http://instance-data/latest/meta-data/public-ipv4/|grep .
Solution 4:
You can use instance metadata so you can run the following command from the ec2 instance:
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
curl http://169.254.169.254/latest/meta-data/local-ipv4
Solution 5:
aws ec2 describe-instances --query "Reservations[].Instances[][PublicIpAddress]"
