Support of aws/gcp

[talset]

To allow authentification on AWS (EKS) & GCP (GKE), it would be nice to install the following packages

Add of aws-iam-authenticator

curl -s -L -o /usr/local/bin/aws-iam-authenticator "https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/download/${AWS_IAM_AUTHENTICATOR_VERSION}/aws-iam-authenticator_$(echo "$AWS_IAM_AUTHENTICATOR_VERSION" | tr -d v)_linux_amd64" && \
    chmod +x /usr/local/bin/aws-iam-authenticator && \
    aws-iam-authenticator version

Add gcloud

    # Download and install gcloud
    curl -sSL https://sdk.cloud.google.com > ./install.sh && \
    bash install.sh --disable-prompts --install-dir=/opt && \
    ln -s /opt/google-cloud-sdk/bin/gcloud /usr/local/bin/gcloud && \
    gcloud --version

Update the param to add

aws_access_key_id
aws_secret_access_key
aws_session_token

gcp_credentials_json
gcp_credentials_json_file

And then, update the out to auth before running kubectl

export AWS_ACCESS_KEY_ID=...
export AWS_SECRET_ACCESS_KEY=...
export AWS_SESSION_TOKEN=...

gcloud auth activate-service-account --key-file="$GOOGLE_APPLICATION_CREDENTIALS"
