+## Graviton-based self-hosted github action worker
+
+### Step 1. Create an EC2 instance with Graviton
+
+Create an AWS Graviton-based EC2 instance. For example,
+
+```
+# or download from https://github.com/aws/aws-k8s-tester/releases
+cd ${HOME}/go/src/github.com/aws/aws-k8s-tester
+go install -v ./cmd/ec2-utils
+
+# create arm64 AL2 instance
+AWS_K8S_TESTER_EC2_ON_FAILURE_DELETE=true \
+AWS_K8S_TESTER_EC2_LOG_COLOR=true \
+AWS_K8S_TESTER_EC2_REGION=us-west-2 \
+AWS_K8S_TESTER_EC2_S3_BUCKET_CREATE=true \
+AWS_K8S_TESTER_EC2_S3_BUCKET_CREATE_KEEP=true \
+AWS_K8S_TESTER_EC2_REMOTE_ACCESS_KEY_CREATE=true \
+AWS_K8S_TESTER_EC2_ASGS_FETCH_LOGS=false \
+AWS_K8S_TESTER_EC2_ASGS='{"GetRef.Name-arm64-al2-cpu":{"name":"GetRef.Name-arm64-al2-cpu","remote-access-user-name":"ec2-user","ami-type":"AL2_arm_64","image-id-ssm-parameter":"/aws/service/ami-amazon-linux-latest/amzn2-ami-hvm-arm64-gp2","instance-types":["m6g.xlarge"],"volume-size":40,"asg-min-size":1,"asg-max-size":1,"asg-desired-capacity":1}}' \
+AWS_K8S_TESTER_EC2_ROLE_CREATE=true \
+AWS_K8S_TESTER_EC2_VPC_CREATE=true \
+ec2-utils create instances --enable-prompt=true --auto-path
+```
+
+### Step 2. Install github action on the host
+
+SSH into the instance, and install the github action self-hosted runner (see [install scripts](https://github.com/etcd-io/etcd/settings/actions/runners/new?arch=arm64&os=linux)).
+
+### Step 3. Configure github action on the host
+
+SSH into the instance, and configure the github action self-hosted runner.
+
+First, we need disable ICU install (see [actions/runner issue on ARM64](https://github.com/actions/runner/issues/629)):
+
+```
+sudo yum install -y patch
+```
+
+And write this bash script:
+
+```

+
+```
+patching file bin/Runner.Listener.runtimeconfig.json
+patching file bin/Runner.PluginHost.runtimeconfig.json
+patching file bin/Runner.Worker.runtimeconfig.json

+

+```
+sudo yum install -y wget

+echo ${INSTANCE_ID}

+--name ${INSTANCE_ID} \
+--labels self-hosted,linux,ARM64,graviton2 \
+--url https://github.com/etcd-io/etcd \
+--token ...
+```
+
+And run:
+
+```
+# run this as a process in the terminal
+cd ${HOME}/actions-runner
+./run.sh
+
+# or run this as a systemd service
+cd ${HOME}/actions-runner
+sudo ./svc.sh install
+sudo ./svc.sh start
+sudo ./svc.sh status
+```
+
+### Step 4. Create github action configuration
