Docker

This section show how to start a cluster node and a standard aggregator with docker

Howto test Gandalf API using docker

simply run

./prepare_docker.sh

It buids a gandalfdocker image. You can run a container to use the API endpoint on localhost:9203 :

run docker run -p 127.0.0.1:9203:9203/tcp gandalfdocker

You should obtain a "hello world" response in your browser using the adreess "http://127.0.0.1:9203/ditrit/Gandalf/1.0.0/".

Getting started

This section show how to start 3 cluster node, 1 standard aggregator, 1 custom aggregator, and 1 connector

Initialisation :

./mkinstall.sh

./gandalf.sh cluster

Change user :

sudo -su gandalf

Cluster :

Cluster initialisation

./gandalf start cluster --offset 1

Standard Aggregator initilisation

./gandalf start aggregator --offset 4 -l gandalf -t gandalf --cluster 127.0.0.1:9100 --secret <secret_output_cluster>

CLI authentification

./gandalf cli -e http://localhost:9203 login <login_output_cluster> <password_output_cluster>

Create cluster2 secret

./gandalf cli -e http://localhost:9203 -t <token_output_login> create secret  

Cluster 2 start

./gandalf start cluster --offset 2 -l Cluster --join 127.0.0.1:9100 --secret <secret>

Create cluster3 secret

./gandalf cli -e http://localhost:9203 -t <token_output_login> create secret  

Cluster 3 start

./gandalf start cluster --offset 3 -l Cluster --join 127.0.0.1:9100 --secret <secret>

Tenant :

Create tenant

./gandalf cli -e http://localhost:9203 -t <token> create tenant <name> <shortdescription> <description>

Aggregator :

Upload configuration

./gandalf cli -e http://localhost:9203 -t <token_output_login> create logicalcomponent <tenant> aggregator <path_to_configuration> 

Aggregator configuration example :

model:
logicalname: aggregator1
type: aggregator
pivot:
  name: aggregator
  major: 1
  minor: 0
keyvalues:
- model:
  value: https://raw.githubusercontent.com/ditrit/gandalf-workers/master 
  key:
    name: repository_url

Create Aggregator secret

./gandalf cli -e http://localhost:9203 -t <token_output_login> create secret  

Aggregator start

./gandalf start aggregator --offset 5 -l <name> -t <tenant> --cluster 127.0.0.1:9100 --secret <secret>

Connector :

Upload configuration

./gandalf cli -e http://localhost:9203 -t <token_output_login> create logicalcomponent <tenant> connector <path_to_configuration> 

Connector configuration example :

model:
logicalname: connector2
type: connector

- model:
  name: tata

Upload configuration

./gandalf cli -e http://localhost:9203 -t <token_output_login> create secret  

Connector start

./gandalf start connector --offset 6 -l <name> --aggregator 127.0.0.1:9103 --secret <secret> --class <class> --product <product>

Demo

This section show how to start a cluster node, a standard aggregator and 2 connectors (github/workflow). Once the 2 connectors started u can upload the example workflow at http://localhost:8080/gandalf/upload to create a repository on Github

Initialisation :

./mkinstall.sh

./gandalf.sh cluster

Change user :

sudo -su gandalf

Cluster :

Cluster initialisation

./gandalf start cluster --offset 1

Standard Aggregator initilisation

./gandalf start aggregator --offset 4 -l gandalf -t gandalf --cluster 127.0.0.1:9100 --secret <secret_output_cluster>

CLI authentification

./gandalf cli -e http://localhost:9203 login <login_output_cluster> <password_output_cluster>

ConnectorGithub :

Upload configuration

./gandalf cli -e http://localhost:9203 -t <token_output_login> create logicalcomponent gandalf connector <path_to_configuration>

  key:
    name: token

Upload configuration

./gandalf cli -e http://localhost:9203 -t <token_output_login> create secret  

Connector start

./gandalf start connector --offset 5 -l connectorgithub --aggregator 127.0.0.1:9103 --secret <secret> --class vcs --product github

ConnectorWorkflow :

Upload configuration

./gandalf cli -e http://localhost:9203 -t <token_output_login> create logicalcomponent gandalf connector <path_to_configuration>
