raykao / run_consul.sh
Created April 5, 2019 05:44
Work around for using Azure Managed Service Identities to discover Consul Server IP addresses. Waiting for [this](https://github.com/hashicorp/go-discover/pull/102) PR on go-discover to be approved
## The Env Vars
# AZURE_SUBSCRIPTION_ID
# CONSUL_VMSS_RG
# CONSUL_VMSS_NAME
## were prepended to this script at provisioning time with Terraform via custom_data/cloud-init
AZURE_MSI_ENDPOINT="http://169.254.169.254/metadata/identity"
AZURE_MSI_OAUTH=$(curl -H "Metadata:true" $AZURE_MSI_ENDPOINT"/oauth2/token?api-version=2018-02-01&resource=https%3A%2F%2Fmanagement.azure.com%2F")
AZURE_MSI_JWT=$(echo $AZURE_MSI_OAUTH | jq -r '.access_token')

# This script is only tested on CentOS 6.5
# You can customize variables such as MOUNTPOINT, RAIDCHUNKSIZE and so on to your needs.
# You can also customize it to work with other Linux flavours and versions.
# If you customize it, copy it to either Azure blob storage or Github so that Azure
# custom script Linux VM extension can access it, and specify its location in the
# parameters of powershell script or runbook or Azure Resource Manager CRP template.
