Nemerosa Infrastructure definition

Overview

Configuration

Create a terraform.tfvars file with following values:

do_token = "your-api-token"

# docker-1.13.1-experimental
do_image = "22776331"

swarm_master_count = 1
swarm_agent_count = 2

Generate a SSH key:

ssh-keygen -t rsa -f ./do-key -N ""

This creates a key pair: do-key (private key) and do-key.pub (public key).

Procedure

Get all Terraform modules:

terraform get

Configure any variable you need in the terraform.tfvars file (see above), according to the definitions found in the vars.tf file.

When done, create the Swarm by running:

terraform apply

After a new minutes, the Docker Swarm stacks are deployed and ready.

Stacks

Following stacks are available:

Stack	URL	Notes
InfluxDB	http://influxdb.ci.nemerosa.net	(1) (2)
Grafana	http://grafana.ci.nemerosa.net	(1)
Jenkins	http://jenkins.ci.nemerosa.net	(1)
Ontrack	http://ontrack.ci.nemerosa.net	(1)

(1) This stack is not redeployable since it needs some shared storage between the nodes.

(2) The InfluxDB availability can be tested using:

curl -v http://swarm.ci.nemerosa.net/influxdb

Appendixes

SSH Connection

In order to connect to the Swarm using SSH:

./swarm-ssh.sh

The script can also be used to run a command remotely:

./swarm-ssh.sh docker service ls

Roadmap

Non functional:

• ❏ SSH proxy using Let’s Encrypt

• ❏ Logging services (ELK)

• ❏ Grafana & Prometheus

• ❏ File storage

• ❏ Health checks & synchronizations

Functional:

• ❏ Jenkins

• ❏ Artifactory

• ❏ Ontrack default configuration

• ❏ Vault & Ontrack integration (would remove need for file storage)

• ❏ Jenkins default configuration

• ❏ Artifactory default configuration
