awlessA Mighty CLI for AWS
awless
is a powerful, innovative and small surface command line interface (CLI) to manage Amazon Web Services.
Why awless
awless
stands out by having the following characteristics:
- small and hierarchical set of commands
- a simple/powerful text templating language to create and revert fully-fledged infrastructures
- wrapping/composing AWS API calls when necessary to enrich behaviour. Ex: ensure smart defaults, security best practices, etc.
- local log of all your cloud modifications done through
awless
to list/revert past actions - sync to a local graph storage of your cloud representation
- exploration of your cloud infrastructure and resources interrelations, even offline using the local graph storage
- clearer and flexible terminal output's with: numerous formats (machine/human friendly), enriched resources's properties/relations when feasible
- connect easily using awless' smart SSH to your private & public instances

compares to other tools, etc.)
Install
Choose one of the following options:
- On macOS, use homebrew:
brew tap wallix/awless; brew install awless
- With
curl
(macOS/Linux), run:curl https://raw.githubusercontent.com/wallix/awless/master/getawless.sh | bash
- Download the latest
awless
binaries (Windows/Linux/macOS) from Github - If you have Golang already installed, install from the source with:
go get -u github.com/wallix/awless
If you have previously used the AWS CLI or aws-shell, you don't need to configure anything! Your config will be automatically loaded (i.e. ~/.aws/{credentials,config}) and awless
will prompt for any missing info (more at our getting started).
Main features
Note that the video above is in APNG and requires a recent browser.
-
Aliasing of resources through their natural name so you don't have to always use cryptic ids that are impossible to remember
-
awless show
: Explore the properties, relations, dependencies of a specific resource (even offline thanks to the sync) given only a name (or id/arn).$ awless show jsmith --local
-
awless list
: Clear and easy listing of multi-region cloud resources (subnets, instances, users, buckets, records, etc.) on AWS EC2, IAM, S3, RDS, AutoScaling, SNS, SQS, Route53, CloudWatch, CloudFormation, Lambda, etc. Listing filters via resources properties or resources tags.$ awless list instances --sort uptime --local $ awless list users --format csv --columns name,created $ awless list volumes --filter state=use --filter type=gp2 $ awless list volumes --tag-value Purchased $ awless ls vpcs --tag-key Dept --tag-key Internal --format tsv $ awless ls instances --tag Env=Production,Dept=Marketing $ awless ls instances --filter state=running,type=micro --format json $ awless ls s3objects --filter bucket=pdf-bucket -r us-west-2 $ ... (see awless ls -h)
-
awless run
: Create, update and delete complex infrastructures with smart defaults and sound auto-complete through awless templates.$ awless run ~/templates/my-infra.aws $ awless run https://raw.githubusercontent.com/wallix/awless-templates/master/linux_bastion.aws etc.
-
Hundreds of powerful CRUD CLI one-liners integrated in the awless templating engine:
$ awless create instance -h $ awless create vpc -h $ awless attach policy -h $ ... (see awless -h)
-
awless log
: Detailled and easy reporting of all the CLI template executions -
awless revert
: Revert of executed templates and resources creation -
Create instances straight from a distro name. No need to know the region or AMI ;) (free tier community bare distro only, see
awless create instance -h
)$ awless create instance distro=debian $ awless create instance distro=coreos $ awless create instance distro=redhat::7.2 type=t2.micro $ awless create instance distro=debian:debian:jessie lock=true $ awless create instance distro=amazonlinux:amzn2 etc.
-
Leveraging AWS
userdata
to provision instance on creation from remote (i.e http) or local scripts:awless create instance ... userdata=/home/john/...
-
awless ssh
: Clean and simple SSH to public & private instances using only a name$ awless ssh my-production-instance $ awless ssh redis-prod --through jump-server $ awless ssh 34.215.29.221 $ awless ssh db-private --private $ awless ssh 172.31.77.151 --port 2222 --through my-proxy --through-port 23 $ ... (see awless ssh -h)
-
awless switch
: Switch easily between AWS accounts (i.e. profile) and regions$ awless switch admin eu-west-2 $ awless switch us-west-1 $ awless switch mfa etc.
-
awless
transparently syncs cloud resources locally to a graph representation in order for the CLI to leverage data and their relations in other awless commands and in an offline manner (more on the sync) -
awless sync
: Explicit and manual command to fetch & store resources locally. Then query & inspect your cloud offline -
Output listing formats either human (default display is Markdown-compatible tables) or machine readable (csv, tsv, json, ...):
--format
-
awless inspect
: Leverage experimental and community inspectors which are interface implementation utilities to run analysis on your cloud resources graphs$ awless inspect -i bucket_sizer (see awless inspect -h)
-
awless completion
: CLI autocompletion for Unix/Linux's bash and zsh

FAQ
Here is a compilation of the question we often answer (thanks for asking them so that we can make things clearer!):
There are already some AWS CLIs. What is awless
unique approach?
Three things that differentiates awless
from other AWS CLIs:
- It has its own compiled and very simple templating language to build AWS infrastructures.
- Commands are made of VERB + ENTITY [+ param=value] and are actually valid lines of the template language.
- It transparently syncs to a local graph a representation of the cloud resources and their relations.
Leveraging and combining the points above, awless
lays some strong foundations for plenty of current/future features/characteristic such as:
- Wrapping AWS API calls to enrich them with before/after behaviour when interacting with the cloud
- Having a small and hierarchical set of commands to intuitively interact with AWS
- Enriching listing of resources using the local model and relations that are not calculated with other CLIs
- Referencing and finding resources quickly avoiding cryptic IDs in favor of names, etc.
- Exposing in the terminal relation between resources: lineage, siblings, etc.
- Performing local analysis of your cloud
- Having a smart SSH to easily connect to instances
- etc.
How do you create infrastructure with awless
?
You build infrastructure using template files
or command one-liners
that get compiled and run through awless
builtin engine. See what the templating language looks like. Learn more about the way templates work
Note that all your actions against the cloud are logged. Templates are revertible/rollbackable.
How does awless
compares to aws-shell
or saws
?
(Points above should also help answering this question)
aws-shell
and saws
are directly mapped to the official AWS CLI. Their only objective is to make you productive and help you manage exhaustively the sheer number of AWS services, options, etc.
awless
addresses this UI/productivity concern differently: small and hierarchical set of commands; favoring enriched listing with relations showing over AWS exhaustive outputting of properties; more useful human/machine formats.
The main point is that the UI/productivity concern is just a feature of awless and not its primary or only one, so there is much more to the tool.
Also aws-shell
and saws
are exhaustive in their support of AWS services. awless
is so far more infrastructure centric, with an emphasis on enriching the information about your real infrastructure. awless
is able to add any new AWS service quickly if that fits and make sense (see wiki on how to add a new AWS service).
How does awless
compares to Terraform?
Terraform is a great product! awless
is much younger than Terraform and Terraform is much broader in scope.
The approach is different though. When creating insfrastructure awless
:
- favors simplicity with a straight forward, compiled and simple deployment language
- employs an all-or-nothing deployment: do not keep state, etc.
-
awless
does provide a rollback on any ran template.
Does awless
handles state when creating infrastructure (i.e. keep track of the changes)?
Quoting from a logz.io/blog entry: "Terraform is an amazing tool but a major challenge is managing the state file. Whenever you apply changes to your infrastructure, the entire managed body of code and created objects are tracked in the Terraform State file (.tfstate), which can reach hundreds of thousands of lines and must be managed carefully lest you incur large merge conflicts or unwanted resource changes", Ofer Velich.
As for now with awless
, we have taken a different path: awless
does not keep state of your cloud; it is more of an all-or-nothing deployment solution.
Note that awless
logs (through rich and revertable logs) all your actions against the cloud and that you can revert any template ran.
