Elastic Block Storage (EBS)
The default storage you’ll get when you create an EC2 instance. An EBS volume resides only in one Availability Zone, so it’s not suitable for cross-AZ redundancy. It’s like a directly-attached drive.
Elastic File System (EFS)
Amazon’s equivalent of NFS. It’s a shared network volume that is replicated across Availability Zones. It’s like a network drive.
Kinesis Client Library. The developer library used for accessing Kinesis Data Streams.
Kinesis Data Streams
Managed data intake pipeline (like Kafka?). You can scale streams up or down so you don’t lose messages, etc.
Kinesis Data Firehose
For delivering streaming data to S3, Redshift, Elasticsearch, Splunk.


Using the awscli Docker image

alias aws='docker run --rm -it -v ~/.aws:/root/.aws -v $(pwd):/aws amazon/aws-cli'
export AWS_DEFAULT_PROFILE=myprofile

# Then run any command using 'aws ...'
aws iam get-user

Installation on RHEL

To install AWS CLI on RHEL (using Python 2.x and pip):

curl -O
python --user
export PATH=~/.local/bin:$PATH
source ~/.bash_profile    # optional
pip install awscli --upgrade --user

Installation on MacOS

awscli can be found in Homebrew.

It can be updated like this:

brew upgrade awscli


Tool version

aws --version

Get the current user details or STS token

$ aws iam get-user
    "User": {
        "Path": "/",
        "UserName": "jeffrey",
        "Arn": "arn:aws:iam::123456789000:user/jeffrey",
        "CreateDate": "2019-09-19T13:00:05Z"

$ aws sts get-current-identity
    "UserId": "123456789000",
    "Account": "123456789000",
    "Arn": "arn:aws:iam::123456789000:root"

EC2: Fetching instance info from an EC2 instance

Fetch the instance ID:

curl -s


Start a cluster

export AWS_DEFAULT_PROFILE=myprofile
eksctl create cluster

Listing clusters

$ aws eks list-clusters --profile myprofile --region eu-west-1
    "clusters": [

Set up kubeconfig to authenticate to an EKS cluster

First install aws-iam-authenticator. Then:

$ export AWS_DEFAULT_PROFILE=profile-for-this-customer
$ alias aws='docker run --rm -it -v ~/.aws:/root/.aws -v $(pwd):/aws amazon/aws-cli'
$ aws eks update-kubeconfig --name cillablack
# This should add the cluster to kubeconfig and switch the context to it.


# Check that the config has been added to kubeconfig
$ kubectl config view
# Check that we have a context (an identity/session)
$ kubectl config get-contexts | grep cillablack    
# Get the token from aws-iam-authenticator
$ aws eks get-token --cluster-name cillablack

Adding Kubernetes Dashboard

export DASHBOARD_VERSION="v2.0.0"

kubectl apply -f${DASHBOARD_VERSION}/aio/deploy/recommended.yaml

# Get a token and copy it to the clipboard
aws eks get-token --cluster-name ${CLUSTER_NAME_HERE} | jq -r '.status.token'

# Proxy connections on port 8080 to the cluster
kubectl proxy --port=8080 --address= --disable-filter=true &

Then access: http://localhost:8080/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/

Or this apparently also works according to the docs:

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep eks-admin | awk '{print $1}')

Then access: http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#!/login

SQS: List queues

$ aws sqs list-queues --profile xxxx --region xxxxx
    "QueueUrls": [

SQS: Send a message to a queue

aws sqs send-message --queue-url $QUEUE_URL --message-body "Oh hiya!" --profile xxxx --region xxxx


“error: You must be logged in to the server (Unauthorized)” when authenticating to EKS:

  • If you created the EKS cluster using the AWS web UI, then you need to use this same user when accessing the cluster using the CLI.
  • Ensure the user you’re accessing the cluster as, has been added into the aws-auth ConfigMap in the kube-system namespace.
  • Check your current identity (including ARN) using aws sts get-caller-identity
