Good day time, profs. I am a bit new to aws cli framework. What i need to get via console is a list of available instances in a specified region with a limit number of that type.

For example, command should look like:

aws ec2 describe-available-instances --region us-west-1 --type [t1.micro, c3.4xlarge, etc. If not set - list all types]

and the output will look like:

t1.micro 5

c3.4xlarge 10

m4.4x 20

Had a similar requirement as above, but also wanted to filter on running instances and view the results per region (sorted).

Using some of the awesome responses from @Vladimir-Kovpak, and @ Anthony Neace, I ended up with this, may help someone (those guys helped me)

for region in $(aws ec2 describe-regions --query 'Regions[].RegionName | sort(@)' --output text); \
do echo $region; \
    aws ec2 describe-instances \
        --region "${region}" \
        --filter Name=instance-state-name,Values=running \
        --query 'Reservations[].Instances[].{InstanceType:InstanceType}' \
        | jq -r '.[].InstanceType' \
        | sort \
        | uniq -c \
        | sort -r;
done

... resulting in output similar to below...

ap-northeast-1
ap-northeast-2
ap-south-1
ap-southeast-1
   5 m3.medium
   4 m4.xlarge
   3 t2.micro
   2 t2.large
   2 t2.medium
   2 m3.large
   1 t2.xlarge
   1 t2.small
   1 m4.large
ap-southeast-2
   5 t2.medium
   4 m4.xlarge
   3 t2.micro
   2 t2.large
   2 m3.medium
   2 m3.large
   1 t2.xlarge
   1 t2.small
   1 m4.large
ca-central-1
eu-central-1
eu-west-1
eu-west-2
eu-west-3
sa-east-1
us-east-1
us-east-2
us-west-1
us-west-2

Also, to save having to paste this in each time, I added it to my aws alias file. Run on the cli with:

aws all

Example below. (create at $HOME/.aws/cli/alias) See the aws cli alias github repo for details (and more great time saving aliases)

# Add to your existing, or create this file at $HOME/.aws/cli/alias

[toplevel]


# Run, with 'aws who'
who = sts get-caller-identity

# Run, with 'aws all'

all = ! 
  ! g() {
    for region in $(aws ec2 describe-regions --query 'Regions[].RegionName | sort(@)' --output text); \
    do echo $region; \
      aws ec2 describe-instances \
          --region "${region}" \
          --filter Name=instance-state-name,Values=running \
          --query 'Reservations[].Instances[].{InstanceType:InstanceType}' \
          | jq -r '.[].InstanceType' \
          | sort \
          | uniq -c \
          | sort -r;
        done
      }; g
