aws cli

installation of AWS cli

aws cli is a python application

# installation
sudo apt install awscli
pip install awscli
# set up user
aws configuration

use aws cli from docker image, aws cli without installation

docker run --rm -it  -v $(pwd):/aws  public.ecr.aws/aws-cli/aws-cli --version
# share local credentials with docker container 
docker run --rm -it  -v $(pwd):/aws  -v ~/.aws:/root/.aws public.ecr.aws/aws-cli/aws-cli command

console command completion, console completion

pip3 install awscli
# complete -C `locate aws_completer` aws
complete -C aws_completer aws

aws cli config

be aware about precedence:

  1. Credentials from environment variables have precedence over credentials from the shared credentials and AWS CLI config file.
    env variables: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html
  2. Credentials specified in the shared credentials file have precedence over credentials in the AWS CLI config file.

datasync

move large amounts of data between on-premises storage and AWS storage services
DataSync configuration can be set up via AWS Management Console

aws-cli-doc
aws-faq
aws-console
aws-feature

datasync links

steps

  1. download datasync agent image DataSync -> Agents -> Create agent -> Deploy Agent
    1. download image
    2. start image in player
      1. install Oracle VM Virtual Box
      sudo apt install virtualbox
      1. File > Import Appliance…
      2. for entering into VM (ssh): 
        DATASYNC_AGENT_IP=192.168.178.48
DATASYNC_SSH_USER=admin
DATASYNC_SSH_PASS=password
sshpass -p ${DATASYNC_SSH_PASS} ssh ${DATASYNC_SSH_USER}@${DATASYNC_AGENT_IP}
  2. activate datasync agent
    1. via ssh
    2. via curl ( select CLI )
    DATASYNC_AGENT_IP=192.168.178.48
ACTIVATION_REGION=eu-central-1
curl "http://${DATASYNC_AGENT_IP}/?gatewayType=SYNC&activationRegion=${ACTIVATION_REGION}&no_redirect"

# key 5C6V2-zzzz-yyyy-xxxx-xxxx
  3. register/create DataSync via aws console DataSync -> Agents -> create agent enter your key
  4. DataSync -> Tasks -> Create task
  5. configure DataSync options.
  6. Start, monitor, and review the DataSync task.

Agent

  • An agent is a virtual machine (VM) used to read data from or write data to a location.
  • An agent is used on premises(in cloud) to manage both read and write operations.
  • Agent status: online/offline A location is a:
    • endpoint of a task
    • source
    • destination
    • service used in the data transfer task.
  • DataSync agent overview
    1. TCP: 80 (HTTP) Used by your computer to obtain the agent activation key. After successful activation, DataSync closes the agent's port 80.
    2. TCP: 443 (HTTPS)
      • Used by the DataSync agent to activate with your AWS account. This is for agent activation only. You can block the endpoints after activation.
      • For communication between the DataSync agent and the AWS service endpoint. API endpoints: datasync.$region.amazonaws.com
        Data transfer endpoints: $taskId.datasync-dp.$region.amazonaws.com cp.datasync.$region.amazonaws.com
        Data transfer endpoints for FIPS: cp.datasync-fips.$region.amazonaws.com
        Agent updates: repo.$region.amazonaws.com repo.default.amazonaws.com packages.$region.amazonaws.com
    3. TCP/UDP: 53 (DNS) For communication between DataSync agent and the DNS server.
    4. TCP: 22 Allows AWS Support to access your DataSync to help you with troubleshooting DataSync issues. You don't need this port open for normal operation, but it is required for troubleshooting.
    5. UDP: 123 (NTP) Used by local systems to synchronize VM time to the host time. NTP 0.amazon.pool.ntp.org 1.amazon.pool.ntp.org 2.amazon.pool.ntp.org 3.amazon.pool.ntp.org

Task

Task management/configuration can be set up via:

  • AWS Management Console
  • AWS Command Line Interface (AWS CLI)
  • DataSync API Task configuration settings includes:
  • source
  • destination
  • options
  • filtering (include/exclude)
  • scheduling
  • frequency
  • tags
  • logging Task phases
  • queuing
  • launching
  • preparing
  • transferring
  • verifying (VerifyMode)
  • success/failure

RDS

should be considered DataStorage type like ( see CommandQueryResponsibilitySegregation ):

  • read heavy
  • write heavy

PostgreSQL

!!! important during creation need to set up next parameter:
Additional configuration->Database options->Initial Database ->
default schema - postgres !!! if you have created Public accessible DB, pls, check/create inbound rule in security group: IPv4 PostgreSQL TCP 5432 0.0.0.0/0

EventBridge

Event hub that receives, collects, filters, routes events ( message with body and head ) based on rules
to receiver back, to another serviceS, to apiS ...
Similar to SQS but wider. Offers comprehensive monitoring and auditing capabilities.

terms

  • Event
    A JSON-formatted message that represents a change in state or occurrence in an application or system
  • Event bus A pipeline that receives events from various sources and routes them to targets based on defined rules
  • Event source The origin of events, which can be AWS services, custom applications, or third-party SaaS providers
  • Event pattern A JSON-based structure that is used in rules to define criteria for matching events
  • Schema A structured definition of an event's format, which can be used for code generation and validation
  • Rule Criteria that are used to match incoming events and determine how they should be processed or routed
  • Archive A feature that makes it possible for you to store events for later analysis or replay
  • Target The destination where matched events are sent, which offers options for event transformation, further processing, and reliable delivery mechanisms, including dead-letter queues

Code Commit


how to clone remote repository


    

  1. create new profile (aws_profile_in_aws_credentials) in ~/.aws/credentials
    2. 

  2. execute next commands
    3. 



git config --global credential.helper '!aws codecommit credential-helper $@'
git config --global credential.UseHttpPath true
AWS_PROFILE=aws_profile_in_aws_credentials
git config --global credential.helper "!aws --profile $AWS_PROFILE codecommit credential-helper $@"


    

  1. check your settings:
    2. 



cat ~/.gitconfig
# check the section: 
# [credential]
#         helper = "!aws --profile aws_profile_in_aws_credentials codecommit credential-helper $@"
#         UseHttpPath = true
# !!! should be not like:
# helper = "aws s3 ls --profile aws_profile_in_aws_credentials codecommit credential-helper "

# fix it otherwise
git config --global --edit 


    

  1. clone your repo with https
    2.
