MonetDB docker image on Google Cloud Platform

We want to run the monetdb-r-docker image in the google cloud. There is lots of documentation on the google website on how to set up your environment, so i will not cover that here in detail.

$ gcloud preview container clusters create monetdb-r-docker
  --num-nodes 1 
  --machine-type g1-small

Waiting for cluster creation...done.
Create cluster succeeded!

Next we will create the container configuration file monetdb.json:

{
  "id": "monetdb-r-docker",
  "kind": "Pod",
  "apiVersion": "v1beta1",
  "desiredState": {
    "manifest": {
      "version": "v1beta1",
      "containers": [{
        "name": "monetdb",
        "image": "monetdb/monetdb-r-docker",
        "ports": [{
          "containerPort": 50000,
          "hostPort": 50000
        }]
      }]
    }
  }
}

With this file, we create the container:
gcloud preview container kubectl create -f monetdb.json
Then we can see that the container is being created:

$ gcloud preview container kubectl get pod monetdb-r-docker
POD                 IP                  CONTAINER(S)        IMAGE(S)                   HOST                                                                  LABELS              STATUS              CREATED
monetdb-r-docker    10.24.1.3           monetdb             monetdb/monetdb-r-docker   k8s-monetdb-r-docker-node-1.c.my-project-id.internal/130.211.82.116   <none>              Pending             Less than a second

It will take a few minutes before the container is created.

$ gcloud preview container kubectl get pod monetdb-r-docker
POD                 IP                  CONTAINER(S)        IMAGE(S)                   HOST                                                                  LABELS              STATUS              CREATED
monetdb-r-docker    10.24.1.3           monetdb             monetdb/monetdb-r-docker   k8s-monetdb-r-docker-node-1.c.my-project-id.internal/130.211.82.116   <none>              Running             3 minutes

Then you could login to the node and use the docker commandline tool to check the running container:

$ gcloud compute ssh k8s-monetdb-r-docker-node-1
Warning: Permanently added '130.211.82.116' (ECDSA) to the list of known hosts.
Linux k8s-monetdb-r-docker-node-1 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt4-3~bpo70+1 (2015-02-12) x86_64

=== GCE Kubernetes node setup complete ===

Before we can connect to the database, we need to add a firewall rule:

$ gcloud compute firewall-rules create monetdb-r-node-50000 --allow tcp:50000 --target-tags k8s-monetdb-r-docker-node
Created [https://www.googleapis.com/compute/v1/projects/my-project-id/global/firewalls/monetdb-r-node-50000].
NAME                 NETWORK SRC_RANGES RULES     SRC_TAGS TARGET_TAGS
monetdb-r-node-50000 default 0.0.0.0/0  tcp:50000          k8s-monetdb-r-docker-node

And then we can connect to the database using the mclient tool:

$ mclient -h 130.211.82.116 -u monetdb -ddb
password:
Welcome to mclient, the MonetDB/SQL interactive terminal (unreleased)
Database: MonetDB v11.19.9 (Oct2014-SP2), 'mapi:monetdb://monetdb-r-docker:50000/db'
Type \q to quit, \? for a list of available commands
auto commit mode: on
sql>\q

And once we are done using the database, we cleanup the container to prevent additional costs:

gcloud preview container clusters delete monetdb-r-docker
Waiting for cluster deletion...done.
name: operation-1427629115685-c7f2c2d7
operationType: deleteCluster
selfLink: https://www.googleapis.com/container/v1beta1/projects/123456789/zones/europe-west1-b/operations/operation-1427629115685-c7f2c2d7

zone: europe-west1-b

And the last step is to remove the firewall rule as well:

gcloud compute firewall-rules delete monetdb-r-node-50000
The following firewalls will be deleted:
 - [monetdb-r-node-50000]

Do you want to continue (Y/n)?  y
