awless templates

Repository to collect official, verified and runnable templates for the awless CLI

You need at least awless version v0.1.3 to run those examples

Here are some non exhaustive Examples of what you can do with templates. You can also read more about awless templates

Continuous Integration

On each change all templates are verified & compiled against the latest version of awless.

You can run the verification locally with:

go get github.com/wallix/awless  # if needed
go test -v

Examples

ECS Autoscaling Cluster

-> Minimal awless version required: v0.1.3

Note that the AMI in this template is working only in eu-west-1 region

tags: autoscaling, container, infra

(run it locally with: awless run repo:ECS_autoscaling_cluster -v)

STEPS

First, create the ECS cluster with awless create containercluster name={cluster.name}. Then, create a policy to allow to connect to ECS

policy = create policy name=AWSEC2ContainerServiceforEC2Role effect=Allow resource="*" description="Access for ECS containers" action=[ecs:DeregisterContainerInstance,ecs:DiscoverPollEndpoint,ecs:Poll,ecs:RegisterContainerInstance,ecs:StartTelemetrySession,ecs:Submit*,ecr:GetAuthorizationToken,ecr:BatchCheckLayerAvailability,ecr:GetDownloadUrlForLayer,ecr:BatchGetImage,logs:CreateLogStream,logs:PutLogEvent]

Set role name variable

roleName = AWSEC2ContainerServiceRole

Create a AWS role that applies on a resource

create role name=$roleName principal-service="ec2.amazonaws.com" sleep-after=15

Attach the policy to the role

attach policy arn=$policy role=$roleName

Create the ECS instances launch configuration. The instances must be launched with a userdata file containing:

!/bin/bash
echo ECS_CLUSTER=ecs-cluster-name >> /etc/ecs/ecs.config
launchconfig = create launchconfiguration image=ami-95f8d2f3 keypair={instance.keypair} name=ECSClusterLaunchconfig type={instance.type} userdata={instance.userdata} role=$roleName

Create the scalinggroup

create scalinggroup desired-capacity={scalinggroup.desired-capacity} launchconfiguration=$launchconfig max-size={scalinggroup.desired-capacity} min-size={scalinggroup.desired-capacity} name=ecsClusterScalingGroup subnets={instance.subnets}

Awless readonly group

(run it locally with: awless run repo:awless_readonly_group -v)

STEPS

Here we define a group that allow users in that group to use the awless CLI in a readonly mode (i.e. sync, listing).

Create group name variable:

groupName = AwlessReadOnlyPermissionsGroup

Create the group:

create group name=$groupName

Attach corresponding readonly AWS policies (set of permissions) on group related to the awless services:

attach policy arn=arn:aws:iam::aws:policy/AmazonEC2ReadOnlyAccess group=$groupName
attach policy arn=arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess group=$groupName
attach policy arn=arn:aws:iam::aws:policy/AmazonSNSReadOnlyAccess group=$groupName
attach policy arn=arn:aws:iam::aws:policy/AmazonSQSReadOnlyAccess group=$groupName
attach policy arn=arn:aws:iam::aws:policy/AmazonVPCReadOnlyAccess group=$groupName
attach policy arn=arn:aws:iam::aws:policy/AutoScalingReadOnlyAccess group=$groupName
attach policy arn=arn:aws:iam::aws:policy/IAMReadOnlyAccess group=$groupName

attach policy arn=arn:aws:iam::aws:policy/IAMReadOnlyAccess group=$groupName

Create a postgres instance

-> Minimal awless version required: v0.1.7

Create a private basic postgres instance with firewall. As an example, instance has only basic required properties filled in

(run it locally with: awless run repo:db_postgres -v)

STEPS

Create a new VPC open to Internet to host the subnets

vpc = create vpc cidr=10.0.0.0/16 name=postgres-vpc
gateway = create internetgateway
attach internetgateway id=$gateway vpc=$vpc

Create a route table for this network

rtable = create routetable vpc=$vpc

Enable routing from the Internet

create route cidr=0.0.0.0/0 gateway=$gateway table=$rtable

One public subnet to later deploy or host public applications or a bastion to access your private DBs

pubsubnet = create subnet cidr=10.0.128.0/20 vpc=$vpc name=public-subnet
update subnet id=$pubsubnet public=true

Make the public subnet open to the Internet (through vpc that has an internetgateway)

attach routetable id=$rtable subnet=$pubsubnet

Two private subnet to constitute the dbsubnetgroup hosting the DB

privsubnet1 = create subnet cidr=10.0.0.0/19 vpc=$vpc name=postgres-priv-subnet1 availabilityzone={availabilityzone.1}
privsubnet2 = create subnet cidr=10.0.32.0/19 vpc=$vpc name=postgres-priv-subnet2 availabilityzone={availabilityzone.2}
subnetgroup = create dbsubnetgroup subnets=[$privsubnet1, $privsubnet2] name=PostgresDBSubnetGroup description="DB subnet group hosting postgres instances"

Firewall for the postgres instance

postgres_sg = create securitygroup name=postgres description='Postgres firewall access' vpc=$vpc
update securitygroup id=$postgres_sg inbound=authorize protocol=tcp portrange=5432 cidr=10.0.0.0/16

Create the database and connect to it through: psql --host=? --port=5432 --username=? --password --dbname=?

create database engine=postgres id={database.identifier} subnetgroup=$subnetgroup  password={password.minimum8chars} dbname={database.name} size=5 type=db.t2.small username={database.username} vpcsecuritygroups=$postgres_sg

Create a small jump instance in your public subnet to run command on your postgres DB and give SSH access to this instance with a SSH security group Run the CLI with: awless .... office.ip=$(awless whoami --ip-only)

sshsecgroup = create securitygroup vpc=$vpc description="SSH access from office IP only" name=ssh-from-office
update securitygroup id=$sshsecgroup inbound=authorize protocol=tcp cidr={office.ip}/32 portrange=22
create instance distro=debian keypair={my.keypair} name=jump subnet=$pubsubnet securitygroup=$sshsecgroup type=t2.micro

Then to administrate your DB you can do: $ HOST=$(awless show production --values-for PublicDNS --local) $ awless ssh jump $ sudo apt-get update; sudo apt-get install -y postgresql-client-9.4 $ psql --host={VALUE FROM HOST ABOVE} --port=5432 --username=... --password --dbname=...

Group of instances scaling with CPU consumption

Create an autoscaling group of instances and watch their CPU to dynamically allocate/delete instances when needed.

launchconfig = create launchconfiguration image={instance.image} keypair={instance.keypair} name=scalingLaunchConf type={instance.type}

Create the scalinggroup

create scalinggroup desired-capacity=2 launchconfiguration=$launchconfig max-size={instance.max-number} min-size={instance.min-number} name=instancesScalingGroup subnets={instance.subnets}

Create a scaling policy to add instances (scale-in) and a scaling policy to remove instances (scale-out)

adjustmentType = ChangeInCapacity
scalein = create scalingpolicy adjustment-scaling=1 adjustment-type=$adjustmentType name=policy-scaling-in scalinggroup=instancesScalingGroup
scaleout = create scalingpolicy adjustment-scaling=-1 adjustment-type=$adjustmentType name=policy-step-scaling-2 scalinggroup=instancesScalingGroup

metrics statistic functions

statFunction = Average
alarmThreshold = 75
monitoredMetric = CPUUtilization

Add a monitoring alarm to enable scalein when CPU load is above 75% during 2 * 5 min

create alarm namespace=AWS/EC2 dimensions=AutoScalingGroupName:instancesScalingGroup evaluation-periods=2 metric=$monitoredMetric name=scaleinAlarm operator=GreaterThanOrEqualToThreshold period=300 statistic-function=$statFunction threshold=$alarmThreshold
attach alarm name=scaleinAlarm action-arn=$scalein

Add a monitoring alarm to enable scaleout when CPU load is below 75% during 2 * 5 min

create alarm namespace=AWS/EC2 dimensions=AutoScalingGroupName:instancesScalingGroup evaluation-periods=2 metric=$monitoredMetric name=scaleoutAlarm operator=LessThanOrEqualToThreshold period=300 statistic-function=$statFunction threshold=$alarmThreshold
attach alarm name=scaleoutAlarm action-arn=$scaleout

STEPS

Create a new VPC and make it public with an internet gateway

vpc = create vpc cidr=10.0.0.0/16 name=BastionVpc
gateway = create internetgateway
attach internetgateway id=$gateway vpc=$vpc

Create 2 private subnets each on a different availability zone That is where you will deploy resources only accessible through the bastion

create subnet cidr=10.0.0.0/19 name=PrivSubnet1 vpc=$vpc availabilityzone={availabilityzone.1}
create subnet cidr=10.0.32.0/19 name=PrivSubnet2 vpc=$vpc availabilityzone={availabilityzone.2}

Create the the public subnet hosting the bastion

pubSubnet = create subnet cidr=10.0.128.0/20 name=PubSubnet1 vpc=$vpc availabilityzone={availabilityzone.1}
update subnet id=$pubSubnet public=true

Create a route table (with routing only allowed within VPC by default)

rtable = create routetable vpc=$vpc

Make the public subnet use the route table

attach routetable id=$rtable subnet=$pubSubnet
create route cidr=0.0.0.0/0 gateway=$gateway table=$rtable

Create the firewall with the remote access CIDR applied on each bastion host

bastionSecGroup = create securitygroup vpc=$vpc description=BastionSecGroup name=bastion-secgroup
update securitygroup id=$bastionSecGroup inbound=authorize protocol=tcp cidr={remoteaccess-cidr} portrange=22

create scalinggroup desired-capacity=1 launchconfiguration=$launchConfig max-size=1 min-size=1 name=autoscaling-instances-group subnets=$pubSubnet

Create a dbsubnetgroups

Create 2 subnets on different availability zones to later on constitute the dbsubnet group

(run it locally with: awless run repo:new_dbsubnetgroup -v)

Full CLI example:

run repo:new_dbsubnetgroup.draft first.subnet.cidr=10.0.0.0/25 first.subnet.availabilityzone=us-west-1a second.subnet.cidr=10.0.0.128/25 second.subnet.availabilityzone=us-west-1c vpc.cidr=10.0.0.0/24 vpc.name=myvpc

STEPS

Create a new VPC open to Internet to host the subnets

vpc = create vpc cidr={vpc.cidr} name={vpc.name}
gateway = create internetgateway
attach internetgateway id=$gateway vpc=$vpc
firstsubnet = create subnet cidr={first.subnet.cidr} vpc=$vpc name={first.subnet.name} availabilityzone={first.subnet.availabilityzone}
update subnet id=$firstsubnet public=true
secondsubnet = create subnet cidr={second.subnet.cidr} vpc=$vpc name={second.subnet.name} availabilityzone={second.subnet.availabilityzone}
update subnet id=$secondsubnet public=true

Create a route table for this network

rtable = create routetable vpc=$vpc

Make the subnets open to the Internet (through vpc that has an internetgateway)

attach routetable id=$rtable subnet=$firstsubnet
attach routetable id=$rtable subnet=$secondsubnet
create dbsubnetgroup name={dbsubnetgroup.name} description={dbsubnetgroup.description} subnets=[$firstsubnet, $secondsubnet]

Attach usual readonly AWS policies (set of permissions) on group

When you want your users to have a set of permissions, instead of attaching permissions directly on users it is a good practice and simpler to define a group having those permissions and then adding/removing as needed users from those groups.

tags: access, policy, role

(run it locally with: awless run repo:policies_on_group -v)

STEPS

attach policy service=ec2 access=readonly group={group-name}
attach policy service=s3 access=readonly group={group-name}
attach policy service=sns access=readonly group={group-name}
attach policy service=sqs access=readonly group={group-name}
attach policy service=vpc access=readonly group={group-name}
attach policy service=autoscaling access=readonly group={group-name}
attach policy service=iam access=readonly group={group-name}
attach policy service=rds access=readonly group={group-name}
attach policy service=route53 access=readonly group={group-name}

Create a public network enabling routing from the Internet

tags: infra

(run it locally with: awless run repo:public_subnet -v)

STEPS

Create the subnet

subnet = create subnet cidr={subnet.cidr} vpc={subnet.vpc} name={subnet.name}

Allow instances in this network to have public IP addresses

update subnet id=$subnet public=true

Create a route table for this network

rtable = create routetable vpc={subnet.vpc}
attach routetable id=$rtable subnet=$subnet

Enable routing from the Internet to this subnet

create route cidr=0.0.0.0/0 gateway={vpc.internetgateway} table=$rtable

Create a AWS role with usual readonly policies that applies on a resource

Create a AWS role that applies on a resource (retrieve the account id with awless whoami)

tags: access, policy, role

(run it locally with: awless run repo:role_for_resource -v)

STEPS

roleName = {role-name}

update subnet id=$subnet public=true
routetable = create routetable vpc=$vpc
attach routetable subnet=$subnet id=$routetable
create route cidr=0.0.0.0/0 gateway=$igw table=$routetable

Create a security group and authorize accesses from the Internet for port 22 and 80

secgroup = create securitygroup vpc=$vpc description="authorize ssh and http from internet" name=wordpress-secgroup
update securitygroup id=$secgroup inbound=authorize protocol=tcp cidr=0.0.0.0/0 portrange=22
update securitygroup id=$secgroup inbound=authorize protocol=tcp cidr=0.0.0.0/0 portrange=80

Create keypair and instance

keypair = create keypair name={keypair.name}
create instance name=wordpress-instance subnet=$subnet keypair=$keypair securitygroup=$secgroup userdata=https://raw.githubusercontent.com/zn3zman/AWS-WordPress-Creation/master/WP-Setup.sh

Upload Image from local file

This template uploads on s3 a local VM file (VHD, OVA, VMDK). Then it creates an AMI from the S3 object.

tags: infra, s3

(run it locally with: awless run repo:upload_image -v)

STEPS

Upload the image on s3

bucket = {image.bucket}
imageObject = create s3object bucket=$bucket file={image.filepath}

Create the AMI from the object on S3

import image description={image.description} bucket=$bucket s3object=$imageObject

Create a user with its SDK/Shell access key and console password

tags: access, user

(run it locally with: awless run repo:user -v)

STEPS

username = {user.name}

Create user

create user name=$username

create loginprofile username=$username password={user.console-password}

Create SDK/shell access key

create accesskey user=$username

Create a VPC with its internet routing gateway

tags: infra, VPC

(run it locally with: awless run repo:vpc -v)

STEPS

vpc = create vpc cidr={vpc.cidr} name={vpc.name}
gateway = create internetgateway
attach internetgateway id=$gateway vpc=$vpc

Create a VPC with 3 internal subnets

(run it locally with: awless run repo:vpc_with_subnets -v)

STEPS

Create a new VPC with private subnets (no internet gateway)

vpc = create vpc cidr=10.0.0.0/16 name=vpc_10.0.0.0_16
create subnet cidr=10.0.0.0/24 vpc=$vpc name=sub_10.0.0.0_24 availabilityzone={subnet1.zone}
create subnet cidr=10.0.1.0/24 vpc=$vpc name=sub_10.0.1.0_24 availabilityzone={subnet2.zone}

Highly-available wordpress behind a loadbalancer, with a RDS database

-> Minimal awless version required: v0.1.1

tags: infra, rds, autoscaling

(run it locally with: awless run repo:wordpress_ha -v)

STEPS

dbname={dbname}
dbhost={dbhost}
dbuser={dbuser}
dbpassword={dbpassword}

Create the load balancer with its security group, target group and listener

lbsecgroup = create securitygroup vpc={wordpress.vpc} description="authorize HTTP from the Internet" name=wordpress-lb-securitygroup
update securitygroup id=$lbsecgroup inbound=authorize protocol=tcp cidr=0.0.0.0/0 portrange=80
tg = create targetgroup name=wordpress-workers port=80 protocol=HTTP vpc={wordpress.vpc}
lb = create loadbalancer name=wordpress-loadbalancer subnets={wordpress.subnets} securitygroups=$lbsecgroup
create listener actiontype=forward loadbalancer=$lb port=80 protocol=HTTP targetgroup=$tg

Create the launch configuration for the instances and start it in a scaling group, to ensure having always 2 instances running

launchconf = create launchconfiguration image={instance.image} keypair={wordpress.keypair} name=wordpress-launch-configuration type=t2.micro userdata=https://raw.githubusercontent.com/wallix/awless-templates/master/userdata/wordpress.sh securitygroups={instances.securitygroup}
create scalinggroup desired-capacity=2 launchconfiguration=$launchconf max-size=2 min-size=2 name=wordpress-scalinggroup subnets={wordpress.subnets} targetgroups=$tg
