This provides a template for deploying a Neo4j instance on OpenStack.
You will need to modify variables.tf defaults or you can input variable values by passing them directly using the -var flag.
Download and install Terraform:
$ wget -P /tmp/ https://releases.hashicorp.com/terraform/0.12.13/terraform_0.12.13_linux_amd64.zip
--
$ unzip /tmp/terraform_0.12.13_linux_amd64.zip
$ sudo mv terraform /usr/local/bin/
$ terraform --versionLog in to the OpenStack dashboard, choose the project for which you want to download the OpenStack RC file, and run the following commands:
$ source ~/Downloads/PROJECT-openrc.sh
Please enter your OpenStack Password for project PROJECT as user username:Initialize Terraform:
- Initialize a new or existing Terraform working directory by creating initial files, loading any remote state, downloading modules, etc.
$ terraform init
Initializing...Generate an execution Plan:
- This execution plan can be reviewed prior to running apply to get a sense for what Terraform will do
$ terraform plan
# or with specific variables
terraform plan -var 'pool=public1' \
-var 'image=ubuntu-16.04' \
-var 'flavor=m1.small' \
-var 'volume_size=3' \
-var 'ssh_key_file=./id_rsa_os'Install the OpenStack CLI client and run the following:
To get a list of usable floating IP pools run the command below and take note of the name:
$ openstack network list --external
+--------------------------------------+----------+--------------------------------------+
| ID | Name | Subnets |
+--------------------------------------+----------+--------------------------------------+
| 1352e2cb-4bb1-44e8-a3fe-8f08ec73c2d5 | public1 | 165ab7e5-a9e4-414c-8cac-88cc127453f3 |
+--------------------------------------+----------+--------------------------------------+
To get a list of images available for use run and take note of the name:
$ openstack image listAfterwards apply changes with:
$ terraform apply
# or with specific variables
terraform plan -var 'pool=public1' \
-var 'image=ubuntu-16.04' \
-var 'flavor=m1.small' \
-var 'volume_size=3' \
-var 'ssh_key_file=./id_rsa_os'
...
Outputs:
address = FLOATING-IP
volume_devices = /dev/sdbUpon completion, the above command will output the instances floating IP address.
You will then point your browser to http://FLOATING-IP:7474 to access the Neo4j database web interface!
