Ops - wrapper for Terraform, Ansible, and SSH for cloud automation
Project description
- This article gives a couple options on how to install or setup Terraform on a macOS Sierra system. The first optional way is to use HomeBrew. Which simplifies the install process and makes updating easy too. Homebrew (IF going Homebrew way instead of downloading zip.) Homebrew (Option 1).

ops-cli
version <2.0 Hp envy 5660 firmware update for macos 10.15.ops-cli is a python wrapper for Terraform, Ansible and SSH for cloud automation.
We use multiple tools to manage our infrastructure at Adobe. The purpose of
ops-cli
is to gather the common cluster configurations in a single place and, based on these, interact with the above mentioned tools. In this way, we can avoid duplication and can quickly spin up new clusters (either production or development ones). All we need to do is customize the cluster configuration file (example here).ops-cli
integrates with the Azure and AWS cli, in order to provide inventory, ssh, sync, tunnel and the possibility to run ansible playbooks on a fleet of EC2 instances.It can be used to add a layer of templating (using jinja2) on top of Terraform files. This is useful for removing duplicated code when it comes to spinning up infrastructure across multiple environments (stage/sandbox/prod) and across teams. Useful for both AWS and Kubernetes deployments.- Use cases
- Installing
- Local
- Ops tool installation
- Configuring
- Tool configuration: .opsconfig.yaml
- Inventory
- Terraform
- SSH
- Secrets Management
- Local
- Development
You define a cluster configuration, using a yaml file. The yaml file contains different kind of sections, one for each plugin. For instance, you could have a section for Terraform files, a section for AWS instructions, Kubernetes Helm charts and so forth.
Manage AWS EC2 instances
Once you define your cluster configuration, you can run
ops
commands such as seeing the instance inventory.This would output something like:
Then you can run
ssh
, play
, run
, sync
etc.See examples/features/inventory
Terraform
Run terraform by using hierarchical configs
See examples/features/terraform-hierarchical
Create Kubernetes cluster (using AWS EKS)
See examples/aws-kubernetes
Local
Virtualenv
Here is a link about how to install and use virtualenv:https://virtualenv.pypa.io/en/stable/
Ops tool installation
Python 3
Terraform
Optionally, install terraform to be able to access terraform plugin. See https://www.terraform.io/intro/getting-started/install.htmlAlso for pretty formatting of terraform plan output you can install https://github.com/coinbase/terraform-landscape (use gem install for MacOS)
Using docker image
You can try out
ops-cli
, by using docker. The docker image has all required prerequisites (python, terraform, helm, git, ops-cli etc).To start out a container, running the latest
ops-cli
docker image run:After the container has started, you can start using
ops-cli
:Configuring
AWS
If you plan to use ops with AWS, you must configure credentials for each account

Usage help
To see all commands and a short description run
ops --help
More help
Each sub-command includes additional help information that you can get by running:
ops examples/inventory/aam.yaml sync --help
Tool configuration: .opsconfig.yaml
Some tool settings are available via a .opsconfig.yaml configuration file.The file is looked-up in
/etc/opswrapper/.opsconfig.yaml
, then in ~/.opsconfig.yaml
and then in the project folder starting from the current dir and up to the root dir.All the files found this way are merged together so that you can set some global defaults, then project defaults in the root dir of the project andoverwrite them for individual envs. Eg: ~/.opsconfig.yaml
, /project/.opsconfig.yaml
, /project/clusters/dev/.opsconfig.yaml
Drive genius for mac yosemite.Inventory
The
inventory
command will list all the servers in a given cluster and cache the results for further operations on them (for instance, SSHing to a given node or running an ansible playbook).You can always filter which nodes you want to display or use to run an ansible playbook on, by using the
--limit
argument (eg. --limit webapp
). The extra filter is applied on the instance tags, which includes the instance name.The way
inventory
works is by doing a describe command in AWS/Azure. The describe command matches all the nodes that have the tag 'cluster' equal to the cluster name you have defined.In order to configure it, you need to add the
inventory
section in your cluster configuration file (example here).AWS example
Azure example
Inventory usage
Terraform
Terraform landscape
For pretty formatting of terraform plan output you can install https://github.com/coinbase/terraform-landscape (use gem install for MacOS).To make
ops
use it you need to add terraform.landscape: True
in opsconfig.yaml file.SSH
SSHPass
In case you want to use the OSX Keychain to store your password and reuse across multiple nodes (e.g. running a playbook on 300 nodes and not having to enter the password for every node) follow the tutorial below:
- Open
Keychain Access
app on OSX - Create a new keychain (
File -> New Keychain
), let's sayaam
- Select the
aam
keychain and add a new password entry in this (File -> New Password Item
):
- Name:
idm
- Kind:
application password
- Account:
your_ldap_account
(e.g.johnsmith
) - Where:
idm
- Create
$HOME/bin
dir - this is where the scripts below are saved Teamviewer for el capitan. - Create
~/bin/askpass
script and update the ldap account there:
- Checkout notty github repo, build and move the binary to
$HOME/bin/
- Bypass software for android download. Create
~/bin/sshpass
script:
- Verify the setup works:
- Run

Secrets Management
There are cases where you need to reference sensitive data in your
cluster.yaml
file (credentials, passwords, tokens etc). Given that the cluster configuration file can be stored in a version control system (such as Git), the best practice is to not put sensitive data in the file itself. Instead, we can use ops-cli
to fetch the desired credentials from a secrets manager such as Vault or Amazon SSM, at runtime.Vault
Ops can manage the automatic generation of secrets and their push in Vault, without actually persisting the secrets in the cluster file.A cluster file will only need to use a construct like the following:
Which will translate behind the scenes in :
- look up in vault the secrets at secret/campaign/generated_password in the default key 'value' (Adobe convention that can be overridden with the key parameter)
- if the value there is missing, generate a new secret using the engine passgen with a policy of length 128 characters
- return the generated value
- if the value at that path already exist, just return that value.This allows us to just refer in cluster files a secret that actually exists in vault and make sure we only generate it once - if it was already created by os or any other system, we will just use what is already there.The reference is by means of fixed form jinja call added to the cluster file, which ends up interpreted later during the templating phase.
Amazon Secrets Manager (SSM)
Amazon offers the possibility to use their Secrets Manager in order to manage configuration data such as credentials, passwords and license keys.
We can use
ops-cli
to fetch the sensitive data from SSM, at runtime. Just define this in your cluster configuration file (eg. mycluster.yaml
).ops-cli
will read the SSM value by running a command similar to: AWS_PROFILE=aam-npe aws ssm get-parameter --name '/my/ssm/path' --region us-east-1 --with-decryption
.Note that you can specify the AWS region via read_ssm(aws_profile='myprofile', region_name='us-west-2')
.Using jinja2 filters in playbooks and terraform templates
https://lockeryellow.weebly.com/mac-download-imessages-from-iphone-2016.html. You can register your own jinja2 filters that you can use in the cluster config file, terraform templates and ansible playbooks
All ops commands look for filters in the following locations:
- the python path
- the .opsconfig.yaml ansible.filter_plugins setting (defaults to plugins/filter_plugins)
Example simple filter:

Install Homebrew
Paste that in a macOS Terminal or Linux shell prompt.The script explains what it will do and then pauses before it does it. Read about other installation options.What Does Homebrew Do?
Homebrew installs the stuff you need that Apple (or your Linux system) didn’t. https://xysoha.weebly.com/does-the-ipad-4-come-with-garageband.html.- Homebrew installs packages to their own directory and then symlinks their files into
/usr/local
. - Homebrew won’t install files outside its prefix and you can place a Homebrew installation wherever you like.
- It's all Git and Ruby underneath, so hack away with the knowledge that you can easily revert your modifications and merge upstream updates.
- Homebrew complements macOS (or your Linux system). Install your RubyGems with
gem
and their dependencies withbrew
. - 'To install, drag this icon.' no more.
