I am trying to find a way to perform a simultaneously copy of a AMI to all other regions.
I have search near and far but beside seeing on a blog post that it can be done, I haven't found a way using aws cli ...
https://aws.amazon.com/blogs/aws/ec2-ami-copy-between-regions/
Currently I have written a bash script to do so, but I would like to find a better, easier way to do so
I have 8 AMI's that need to be passed to all regions.
using an array-
declare -a DEST=('us-east-1' ...2....3)
aws copy-image --source-region $SRC --region ${DESTx[#]} --source-ami-id $ami
Do you guys have any other suggestion?
Thanks.
you can make a single line bash, specially useful if in future there are new regions:
aws ec2 describe-regions
--output text |\
cut -f 3 | \
xargs -I {} aws copy-image
--source-region $SRC
--region {}
--source-ami-id $ami
basically it goes like this:
aws ec2 describe-regions --output text returns the list of all available regions for ec2, its a 3 columns table ("REGIONS", endpoint, region-name)
cut -f 3 takes the 3rd column of the previous table (read as list)
keep the current region from previous argument (xargs) into {} so you can send it to the region parameter of the copy-image command

I want to use the value of the DOMAIN_ID variable to filter the EFS to get a FileSystemId. I used the commands below. The first command works and it stores the domain ID. The second one returns an empty list, even though the DOMAIN_ID variable is present.
DOMAIN_ID=$(aws sagemaker list-domains --query 'Domains[0].DomainId')
aws efs describe-file-systems --query 'FileSystems[?CreationToken==`$DOMAIN_ID`].FileSystemId'
Output:
[]
Expected output:
<Some EFS identifier>
This works (escaping backticks) -
aws efs describe-file-systems --query "FileSystems[?CreationToken==\`$DOMAIN_ID\`].FileSystemId"
You can also use describe-domain command instead -
$ DOMAIN_ID=$(aws sagemaker list-domains --query 'Domains[0].DomainId' | tr -d '"')
$ aws sagemaker describe-domain --domain-id $DOMAIN_ID --query 'HomeEfsFileSystemId'
I have 2 instances of the same deployment/project on AWS Elastic Beanstalk.
Both contain a Laravel project which contains scheduling code which runs various commands which can be found in the schedule method/function of the Kernel.php class within 'app/Console' - the problem I have is that if a command runs from one instance then it will also run the command from the second instance which is not what I want to happen.
What I would like to happen is that the commands get run from only one instance and not the other. How do I achieve this in the easiest way possible?
Is there a Laravel package which could help me achieve this?
From Laravel 5.6:
Laravel provides a onOneServer method which you can use if your applications share a single cache server. You could use something like ElastiCache to host Redis or Memcached and use it as your cache server for both of your application instances. Then you would be able to use the onOneServer method like this:
$schedule->command('report:generate')
->fridays()
->at('17:00')
->onOneServer();
For older versions of Laravel:
You could use the jdavidbakr/multi-server-event package. Once you have it set up you should be able to use it like:
$schedule->command('inspire')
->daily()
->withoutOverlappingMultiServer();
I had the same issue to run some cronjobs (nothing related to Laravel) and I found a nice solution (don't remember where I found it)
What I do is check if the instance running the code is the first instance on the Auto Scaling Group, if it's the first then I execute the command otherwise just exit.
This is the way it's implemented:
#!/bin/bash
INSTANCE_ID=`curl http://169.254.169.254/latest/meta-data/instance-id 2>/dev/null`
REGION=`curl -s http://169.254.169.254/latest/dynamic/instance-identity/document 2>/dev/null | jq -r .region`
# Find the Auto Scaling Group name from the Elastic Beanstalk environment
ASG=`aws ec2 describe-tags --filters "Name=resource-id,Values=$INSTANCE_ID" \
--region $REGION --output json | jq -r '.[][] | select(.Key=="aws:autoscaling:groupName") | .Value'`
# Find the first instance in the Auto Scaling Group
FIRST=`aws autoscaling describe-auto-scaling-groups --auto-scaling-group-names $ASG \
--region $REGION --output json | \
jq -r '.AutoScalingGroups[].Instances[] | select(.LifecycleState=="InService") | .InstanceId' | sort | head -1`
# If the instance ids are the same exit 0
[ "$FIRST" = "$INSTANCE_ID" ]
Try implementing those calls using PHP and it should work.
This results instances listed with ELB:
aws elb describe-load-balancers --load-balancer-name XXXXXXX --region us-east-1 | jq -r '.LoadBalancerDescriptions[].Instances[].InstanceId'
I need some help in writing a script, which checks for new aws instances attached to the ELB.
- Need to compare the present result and previous results, which helps us to get the new instance info.
I'm trying to remove only the files which are ONLY older than 5 days according to the file name containing "DITN1_" and "DITS1_" time using a bash script within the AWS S3 Bucket but the issue is all the files i'm trying to delete looks like as follows:
DITN1_2016.12.01_373,
DITS1_2012.10.10_141,
DITN1_2016.12.01_3732,
DITS1_2012.10.10_1412
if someone can help me out with the code would be nice.
thanks in advance
You can use aws cli command for deleting stuff using the bash script as follows
aws s3 rm s3://mybucket/ --recursive --include "mybucket/DITN1*"
However it does not support timestamp
For details see aws S3 cli
Is it important to use the name of the objects instead of metadata? You could get a list of objects in the bucket using the s3api:
aws s3api list-objects --bucket example --no-paginate # this last option will avoid pagination, don't use it if you have thousands of objects
Adding
--query Contents[]
Will give you back the contents of every object, including a LastModified section, which will tell you when the object was last modified, for example "2016-12-16T13:56:23.000Z".
http://docs.aws.amazon.com/cli/latest/reference/s3api/list-objects.html
You could change this timestamp to epoch using
date "+%s" -d "put the timestamp here"
And compare it with the current time - 5 days.
OR if you really want to delete objects based on name, you could loop over the keys like this:
for key in $(aws s3api list-objects --bucket example --no-paginate --query Contents[].Key)
And add logic to determine the date. Something like this might work, judging by your examples:
key_without_prefix=${key#*_}
key_without_suffix=${key_without_prefix%_*}
Then you have your date, which you can compare with the current time - 5 days.
I'm writing a bash script that needs to get the private ips of all instances where describe-instances does not return platform=>windows, and store them in an array $ips
This script works so far (just getting the private ips)
ips=$(aws ec2 describe-instances --region $r --filters "Name=tag:Name,Values=*$c*" | jq '.Reservations[].Instances[].NetworkInterfaces[].PrivateIpAddress')
but what I can't figure out is how to exclude windows servers (or, conversely, only include non-windows servers)
Here's what I've tried
--filters "Name=tag:Name,Values=*$c*" "Name=platform,Values="
--filters "Name=tag:Name,Values=*$c*" "Name=platform,Values=null"
--filters "Name=tag:Name,Values=*$c*" "Name=platform,Values=NULL"
I've also tried doing it on the jq side of the pipe, but my attempts were ridiculous and I will not publish them here. I did find out you cannot do more than two filters on that side (unless I messed that up too)
Any ideas?
I don't use AWS so I don't have much to go on but based off of the describe-instances reference, I think this filter should work.
.Reservations[].Instances |
map(select(.Platform != "Windows") | .NetworkInterfaces[].PrivateIpAddress)
