Hi I would like to pipe an instance output to start/stop ec2 instances. Here is the beginning of the code:
aws ec2 describe-instances \
--query "Reservations[*].Instances[*].{Instance:InstanceId,Subnet:SubnetId}" \
--filters "Name=tag-value,Values=<INSTANCE NAME TAG>" \
--output text | \
How do I pipe this output to AWS ec2 start-instances command in Windows?
Output format can be JSON,YAML, TEXT or Table.It depends on your requirements.
Sample command for JSON output:
$ aws iam list-users --output json
Sample output:
{
"Users": [
{
"Path": "/",
"UserName": "Admin",
"UserId": "AIDA1111111111EXAMPLE",
"Arn": "arn:aws:iam::123456789012:user/Admin",
"CreateDate": "2014-10-16T16:03:09+00:00",
"PasswordLastUsed": "2016-06-03T18:37:29+00:00"
},
{
"Path": "/backup/",
"UserName": "backup-user",
"UserId": "AIDA2222222222EXAMPLE",
"Arn": "arn:aws:iam::123456789012:user/backup/backup-user",
"CreateDate": "2019-09-17T19:30:40+00:00"
},
{
"Path": "/",
"UserName": "cli-user",
"UserId": "AIDA3333333333EXAMPLE",
"Arn": "arn:aws:iam::123456789012:user/cli-user",
"CreateDate": "2019-09-17T19:11:39+00:00"
}
]
}
Now if you want to use this output for input of another command, one easy way is to read the json file, extract the value and use that as input to other command.
Please read https://www.business.com/articles/using-powershell-with-json-data/ for some details.
I found a PowerShell solution which suits my needs better:
$InstanceId = aws ec2 describe-instances --query "Reservations[*].Instances[*].{Instance:InstanceId}" --filters "Name=tag-value,Values=<INSTANCE NAME TAG>" --output text aws ec2 start-instances --instance-ids $InstanceId

How can I print only the value of Value attribute from the below output of the following command
aws ssm get-parameter --name "/test/ip/cidr" --profile test
{
"Parameter": {
"Name": "/test/ip/cidr",
"Type": "String",
"Value": "172.18.0.0/20",
"Version": 1,
"LastModifiedDate": 1585251360.78,
"ARN": "arn:aws:ssm:us-east-1:123233:parameter/test/ip/cidr",
"DataType": "text"
}
}
Tried running the below command but prints like [{"Value": "172.18.0.0/20"}] but just want to see only 172.18.0.0/20
aws ssm get-parameters --names "/test/ip/cidr" --query "Parameters[*].{Value:Value}" --profile test
[
{
"Value": "172.18.0.0/20"
}
]
You can add --output text and modify your --query:
aws ssm get-parameter --name "/test/ip/cidr" --profile test \
--query "Parameter.Value" --output text
My Stack Outputs:
"Outputs": [
{
"OutputKey": "InstanceId",
"OutputValue": "i-0ed2834d95ae5bb98",
"Description": "Instance Id"
},
{
"OutputKey": "PrivateIp",
"OutputValue": "10.176.66.46",
"Description": "Private IP address"
},
{
"OutputKey": "EbsVolumeId",
"OutputValue": "vol-03837489a20032881",
"Description": "EbsVolume"
}
I tried to query the PrivateIp of stack by using the command below but the command doesn't return anything.
aws cloudformation describe-stacks --stack-name my-stack-01 --query "Stacks[0].Outputs[?OutputKey=="PrivateIp"].OutputValue" --output text
What did I do wrong?
Thx in advance!
You must use single-quotes in the filter part ?OutputKey=="PrivateIp" of your query. So, change your whole query to:
aws cloudformation describe-stacks --stack-name my-stack-01 --query "Stacks[0].Outputs[?OutputKey=='PrivateIp'].OutputValue" --output text
This will work.
I'm trying to parse JSON output from the AWS CLI. What I'm looking for are security group names with specific tags below them. The two commands that work are
$aws ec2 describe-security-groups | jq -r '.SecurityGroups[].GroupName'
default
mysqlsg
apachesg
default
Then I run
$ aws ec2 describe-security-groups | jq -r '.SecurityGroups[].Tags[]|select(.Key == "Service")'
{
"Key": "Service",
"Value": "default"
}
{
"Key": "Service",
"Value": "MySQL"
}
{
"Key": "Service",
"Value": "Apache"
}
{
"Key": "Service",
"Value": "default"
}
I'd like each group to have the Service Tag below it so I tried this but it didn't work.
$ aws ec2 describe-security-groups | jq -r '.SecurityGroups[].GroupName,.SecurityGroups[].Tags[]|select(.Key == "Service")'
jq: error (at <stdin>:225): Cannot index string with string "Key"
You can do this with aws-cli query parameters, try the below and it should work.
aws ec2 describe-security-groups --query 'SecurityGroups[].{Tags:Tags[?Key==`Name`].Value|[0],GroupName:GroupName}'
output
{
"Tags": "demo",
"GroupName": "demo"
}
I need to list EBS VolumeID and the instance that it's attached to using the aws cli. This is the line I used:
aws ec2 describe-volumes --output text --query 'Volumes[*].{VolumeID:VolumeId, Instance:InstanceId}' | head -5
None vol-07210e47
None vol-743d1234
None vol-933d12d3
None vol-493c1309
None vol-1e3b145e
For some reason the instance IDs are showing as none. When the unfiltered output of the command shows that they're there:
aws ec2 describe-volumes | head -25
{
"Volumes": [
{
"AvailabilityZone": "us-east-1d",
"Attachments": [
{
"AttachTime": "2013-09-05T15:17:39.000Z",
"InstanceId": "i-c28e20ae",
"VolumeId": "vol-07210e47",
"State": "attached",
"DeleteOnTermination": false,
"Device": "/dev/sda1"
}
],
What am I doing wrong?
You're not querying into Attachments. This worked for me:
aws ec2 describe-volumes --output text --query 'Volumes[*].Attachments[].{VolumeID:VolumeId,InstanceID:InstanceId}'
This is a good link:

I want to run an ansible role, for all the ip address in the vpc which are running.
How to get all the ip address of running instance in given vpc
Things: I have tired:
aws ec2 describe-instances --filters "Name=vpc-id,
Values="vpc-******"" --query
"Reservations[].Instances[].PrivateIpAddresses[*]" --output text
This is returning null
The name of the parameter is PrivateIpAddress not PrivateIpAddresses as you can see from Json object
[
[
{
"Monitoring": {
"State": "disabled"
},
"PublicDnsName": "xxxx",
"RootDeviceType": "ebs",
"State": {
"Code": 16,
"Name": "running"
},
"EbsOptimized": false,
"LaunchTime": "xxx",
"PublicIpAddress": "xxx",
"PrivateIpAddress": "xxxxx",
"ProductCodes": [
....
so if you run your command as
aws ec2 describe-instances --filters "Name=vpc-id, Values="vpc-cda7c6a8"" --query "Reservations[*].Instances[*].PrivateIpAddress" --output text
you will have your expected result
it's PrivateIPAddress, not Addresses
aws ec2 describe-instances --instance-ids --query Reservations[].Instances[].PrivateIpAddress
Hope this helps
