+# Build Packer Images
+
+Note that I needed to do this build from a cloud shell, so clone and then:
+
+```bash
+git clone https://github.com/converged-computing/flux-usernetes
+cd flux-usernetes/azure/build-ubuntu-24.04
+```
+
+And install packer
+
+```bash
+wget https://releases.hashicorp.com/packer/1.11.2/packer_1.11.2_linux_amd64.zip
+unzip packer_1.11.2_linux_amd64.zip
+mkdir -p ./bin
+mv ./packer ./bin/
+export PATH=$(pwd)/bin:$PATH
+```
+
+Get your account information for azure as follows:
+
+```bash
+az account show 
+```
+
+And export variables in the following format. Note that the resource group needs to actually exist - I created mine in the console UI.
+
+```bash
+export AZURE_SUBSCRIPTION_ID=xxxxxxxxx
+export AZURE_TENANT_ID=xxxxxxxxxxx
+export AZURE_RESOURCE_GROUP_NAME=packer-testing
+```
+
+Then build!
+
+```bash
+make
+```
