jungle

Description

jungle makes AWS operations from terminal simpler and more intuitive.

Why created

awscli is by far the most comprehensive CLI tool manipulating various AWS services, and I really like its flexible options and up-to-date release cycle. However, day-to-day AWS operations from my terminal don't need that much flexibility and that many services. Rather, I wanted just small set of UNIX-like commands which are easy to use and remember.

Installation

pip install jungle

Usage

EC2

I would highly recommend to use ssh-agent to manage your ssh keys and pass phrases. If you ssh-add your keys, ssh-agent automatically select appropriate key when you try to login to a box. This makes it much easier to use jungle ec2 ssh, or ssh command in general, since you don't have to specify --key-file /path/to/key.pem for each EC2 instance.

Listing all EC2 instances (each attribute is separated by a tab)

jungle ec2 ls

Listing all EC2 instances in formatted output(each attribute is separated with space and is aligned)

jungle ec2 ls -l

Filtering EC2 instances by Name tag

jungle ec2 ls blog-web-server-01

Filtering EC2 instances by Name tag using wildcard

jungle ec2 ls '*web*'

Starting instance

jungle ec2 up -i i-xxxxxx

Stopping instance

jungle ec2 down -i i-xxxxxx

SSH login to instance specified by instance id

jungle ec2 ssh -i i-xxxxxx --key-file /path/to/key.pem --port 1234

SSH login to instance specified by Tag Name

jungle ec2 ssh -n blog-web-server-01 --key-file /path/to/key.pem

SSH login to instance specified by Tag Name with wildcard (you'll be prompted to choose which server to log in)

jungle ec2 ssh -n 'blog-web-server-*' --key-file /path/to/key.pem

SSH login to instance specified by Tag Name through gateway instance

jungle ec2 ssh -n blog-web-server-01 --key-file /path/to/key.pem -g i-xxxxxx

SSH login to instance specified by Tag Name using auto ssh key discovery

jungle ec2 ssh -n blog-web-server-01

SSH login to instance gateway instance, specifying username for each instance, while disabling known_hosts prompt.

jungle ec2 ssh -i i-xxxxxx -u ec2-user -k /path/to/key.pem -s "-o UserKnownHostsFile=/dev/null" -g i-xxxxxx -x core

--dry-run gives you ssh command and exits.

jungle ec2 ssh -n blog-web-server-01 -u ec2-user --dry-run
ssh xxx.xxx.xxx.xxx@ec2-user

-P/--profile-name specify AWS profile name.

jungle ec2 -P myprofile ssh -n blog-web-server-01 -u ec2-user

ELB

Listing all ELB instances

jungle elb ls

Listing a ELB instance

jungle elb ls production-blog-elb

Listing ELB attached EC2 instances

jungle elb ls -l production-blog-elb

EMR

jungle emr ls

jungle emr ssh -k /path/to/key.pem -i j-xxxxxxx

jungle emr rm -i j-xxxxxxx

AutoScaling

jungle asg ls

RDS

jungle rds ls

Autocompletion (currently only supports bash)

Execuging the following command prints bash autocompletion script. Copy and past or redirect to your favorite file (e.g. /etc/bash_completion.d/jungle, ~/.bashrc). This is a function of click, which internally used by jungle.

$ _JUNGLE_COMPLETE=source jungle

Configuration

You can create the credential file yourself. By default, its location is at ~/.aws/credentials

[default]
aws_access_key_id = YOUR_ACCESS_KEY
aws_secret_access_key = YOUR_SECRET_KEY

You may also want to set a default region. This can be done in the configuration file. By default, its location is at ~/.aws/config

[default]
region = us-east-1

More detailed configurations can be found in the boto3 documentation.
