Directorio superior # AWS Command line interface
## Installation and setup
There are a number of different ways to install the AWS CLI on your machine, depending on what operating system and environment you are using:
On Microsoft Windows – use the MSI installer. On Linux, OS X, or Unix – use pip (a package manager for Python software) or install manually with the bundled installer.
### Install using pip:
You will need python to be installed (version 2, 2.6.5+,3 or 3.3+). Check with
```bash python –version pip –help ```
Given that both of these are installed, use the following command to install the aws cli.
```bash sudo pip install awscli ```
Install on Windows The AWS CLI is supported on Microsoft Windows XP or later. For Windows users, the MSI installation package offers a familiar and convenient way to install the AWS CLI without installing any other prerequisites. Windows users should use the MSI installer unless they are already using pip for package management.
MSI Installer for Windows 32-bit MSI Installer for Windows 64-bit Run the downloaded MSI installer. Follow the instructions that appear.
### To install the AWS CLI using the bundled installer
Prerequisites:
- Linux, OS X, or Unix
- Python 2 version 2.6.5+ or Python 3 version 3.3+
- Download the AWS CLI Bundled Installer using wget or curl.
Unzip the package.
Run the install executable.
On Linux and OS X, here are the three commands that correspond to each step:
```sh curl “https://s3.amazonaws.com/aws-cli/awscli-bundle.zip” -o “awscli-bundle.zip” unzip awscli-bundle.zip sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws ```
Install using HomeBrew on OS X:
Another option for OS X
```sh brew install awscli ```
### Test the AWS CLI Installation
Confirm that the CLI is installed correctly by viewing the help file. Open a terminal, shell or command prompt, enter aws help and press Enter:
aws help
### Configuring the AWS CLI
Once you have finished the installation you need to configure it. You’ll need your access key and secret key that you get when you create your account on aws. You can also specify a default region name and a default output type (text|table|json).
$ aws configure AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY Default region name [None]: us-west-2 Default output format [None]: ENTER
### Updating the CLI tool
Amazon periodically releases new versions of the AWS Tool. If the tool was installed using the Python Pip tool the following command will check the remote repository for updates, and apply it to your local system.
pip install awscli --upgrade
## Using aws cli commands
The syntax for using the aws cli is as follows:
aws [options] <command> <subcommand> [parameters]
Some examples using the ‘ec2’ command and the ‘describe-instances’ subcommand:
aws ec2 describe-instances aws ec2 describe-instances --instance-ids <your-id>
Example with a fake id:
aws ec2 describe-instances --instance-ids i-c71r246a

import an existing keypair
aws ec2 import-key-pair \
--key-name keyname_test \
--public-key-material file:///home/apollo/id_rsa.pub
### Profiles
To setup a new credential profile with the name myprofile :
aws configure --profile myprofile
AWS Access Key ID [None]: ACCESSKEY
AWS Secret Access Key [None]: SECRETKEY
Default region name [None]: REGIONNAME
Default output format [None]: text | table | json
For the AWS access key id and secret, create an IAM user in the AWS console and generate keys for it. Region will be the default region for commands in the format eu-west-1 or us-east-1 . The default output format can either be text , table or json . You can now use the profile name in other commands by using the –profile option, e.g.:
aws ec2 describe-instances --profile myprofile
AWS libraries for other languages (e.g. aws-sdk for Ruby or boto3 for Python) have options to use the profile you create with this method too. E.g. creating a new session in boto3 can be done like this, boto3.Session(profile\_name:‘myprofile’) and it will use the credentials you created for the profile.
The details of your aws-cli configuration can be found in \~/.aws/config and \~/.aws/credentials (on linux and mac-os). These details can be edited manually from there.
### S3
aws s3 --region eu-central-1 cp xxxxx s3://enel-staging-sc/lah/xxxxx --acl public-read aws s3 --region eu-central-1 cp s3://enel-staging-sc/lah/xxxxx xxxxx aws s3 --region eu-central-1 ls s3://enel-staging-sc/lah/xxxxx aws s3 --region eu-central-1 rm s3://enel-staging-sc/lah/xxxxx
Use a named profile
aws --profile myprofile s3 ls
List all objects in a bucket, including objects in folders, with size in human-readable format and a summary of the buckets properties in the end -
aws s3 ls --recursive --summarize --human-readable s3://<bucket_name>/
### Cloudtrail - Logging and Auditing
list all trails
aws cloudtrail describe-trails
create a new trail
aws cloudtrail create-subscription \
--name awslog \
--s3-new-bucket awslog2016
list the names of all trails
aws cloudtrail describe-trails --output text | cut -f 8
get the status of a trail
aws cloudtrail get-trail-status --name awslog
delete a trail
aws cloudtrail delete-trail --name awslog
delete the S3 bucket of a trail
aws s3 rb s3://awslog2016 --force
add tags to a trail, up to 10 tags
aws cloudtrail add-tags \
--resource-id awslog \
--tags-list "Key=log-type,Value=all"
list the tags of a trail
aws cloudtrail list-tags --resource-id-list
remove a tag from a trail
aws cloudtrail remove-tags \
--resource-id awslog \
--tags-list "Key=log-type,Value=all"
### Network Load Balancer
Create your load balancer
aws elbv2 create-load-balancer --name my-load-balancer --type network --subnets subnet-0e3f5cac72EXAMPLE
create a target group, specifying the same VPC that you used for your EC2 instances:
aws elbv2 create-target-group --name my-targets --protocol TCP \ --port 80 --vpc-id vpc-0598c7d356EXAMPLE
register your instances with your target group:
aws elbv2 register-targets --target-group-arn targetgroup-arn \ --targets Id=i-1234567890abcdef0 Id=i-0abcdef1234567890
create a listener for your load balancer with a default rule that forwards requests to your target group:
aws elbv2 create-listener --load-balancer-arn loadbalancer-arn --protocol TCP --port 80 \ --default-actions Type=forward,TargetGroupArn=targetgroup-arn
verify the health of the registered targets for your target group using this
aws elbv2 describe-target-health --target-group-arn targetgroup-arn
Specify an Elastic IP address for your load balancer
aws elbv2 create-load-balancer --name my-load-balancer --type network \ --subnet-mappings SubnetId=subnet-0e3f5cac72EXAMPLE,AllocationId=eipalloc-12345678
Delete your load balancer
aws elbv2 delete-load-balancer --load-balancer-arn loadbalancer-arn aws elbv2 delete-target-group --target-group-arn targetgroup-arn
### Others
aws glacier create-vault --account-id xxxxx --vault-name myvault aws sts get-caller-identity
### Get console output
A useful awscli feature is get-console-output which allows us to view the Linux console of an instance shortly after the instance boots. You will have to pipe the output of get-console-output into sed to correct line feeds and carriage returns.
```
$ aws ec2 get-console-output --instance-id i-0d9c2b31 \ | sed 's/\\n/\n/g' | sed
```
### Completer
```
which aws_completer /usr/local/bin/aws_completer
```
Bundled Installer – if you used the bundled installer per the instructions in the previous section, the AWS completer will be located in the bin subfolder of the installation directory.
```mixed ls /usr/local/aws/bin activate activate.csh activate.fish activate_this.py aws aws.cmd aws_completer ```
If all else fails, you can use find to search your entire file system for the AWS completer.
``` mixed $ find / -name aws_completer /usr/local/aws/bin/aws_completer ```
bash – use the built-in command complete.
``` sh complete -C '/usr/local/bin/aws_completer' aws ```
Note
/usr/local/bin is the default installation directory when you install the AWS CLI with pip. See Locate the AWS Completer (p. 14) if you are not sure where the AWS CLI was installed.
## AWSCLI v2
``` sh curl “https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip” -o “awscliv2.zip” unzip awscliv2.zip sudo ./aws/install ```
