Installing the SQL Server Big Data Cluster Tools in a Docker Container

(Be sure to checkout the FREE SQLpassion Performance Tuning Training Plan - you get a weekly email packed with all the essential knowledge you need to know about performance tuning on SQL Server.)

As you know from my last blog posting, I’m currently investing a lot of my time into Big Data technologies and especially into SQL Server Big Data Clusters. Running a SQL Server Big Data Cluster is quite easy, because you can deploy it with a simple command into Azure Kubernetes Services.

But to be able to do that you need to have a few command line tools installed on your local machine. In the days of Docker, I don’t really like it have too many tools installed locally on my work machine, because I want to have them isolated in a Docker Container. Therefore, I want to show you in today’s blog posting how to install the SQL Server Big Data Cluster Tools in a Docker Container.

Necessary Tools

To be able to deploy and manage a SQL Server Big Data Cluster from the command line, you need to have at least the following 3 tools installed:

  • Azure CLI
  • kubectl
  • azdata

The Azure CLI is used to connect to and manage your Azure Subscription. When you have a Kubernetes Cluster deployed into Azure, you can manage it locally with the kubectl command, which is the command line tool for Kubernetes. And finally, you also need the tool azdata, which is the main command line tool to manage your SQL Server Big Data Cluster.

Creating and configuring the Docker Container

First of all, I have created a new Docker Container which is based on the Linux Ubuntu image:

docker run -t --name bdc_tools -i ubuntu /bin/bash

After I was logged into the newly created Docker Container, I have installed the tool curl:

apt-get update
apt-get install -y curl

The next step is the installation of the Azure CLI, which can be done with the following command line:

curl -sL | bash

After the installation of the Azure CLI, I have logged in into my Azure Subscription:

az login

After the successful login, I’m able to list my Kubernetes Cluster, which is deployed into Azure:

az aks list --output table

The next step is the installation of kubectl, so that you can manage your Kubernetes Cluster from the command line:

curl -LO`curl -s`/bin/linux/amd64/kubectl
chmod +x ./kubectl
mv ./kubectl /usr/local/bin/kubectl

After I have installed kubectl, I had to import the context of my Azure Kubernetes Cluster into my local installation:

az aks get-credentials --resource-group BDC_ResourceGroup --name bdc-cluster

And then I’m able to list my Kubernetes Worker Nodes:

The Kubernetes Worker Nodes

And the final step is the installation of the azdata tool, with which you can manage your SQL Server Big Data Cluster:

apt-get install gnupg ca-certificates curl wget software-properties-common apt-transport-https lsb-release -y
curl -sL | gpg --dearmor | tee /etc/apt/trusted.gpg.d/microsoft.asc.gpg > /dev/null
add-apt-repository "$(wget -qO-"
apt-get update
apt-get install -y azdata-cli

After the installation, you can run azdata from the command line:

Running azdata in a Docker Container

It seems that everything is fine, but unfortunately this is not the case. When I wanted to deploy a SQL Server Big Data Cluster, I got the following error message: cannot open shared object file: No such file or directory

It seems that the shared object file is missing in the Docker Container. The only workaround that I have found was the following: I downloaded that file from here, and copied it with the following command line into the Docker Container:

docker cp libreadline6_6.3-8ubuntu2_amd64.deb bdc_tools:/libreadline6_6.3-8ubuntu2_amd64.deb

After I have attached my terminal again against the Docker Container, I manually installed the .deb file:

apt install ./libreadline6_6.3-8ubuntu2_amd64.deb

And finally, everything is working as expected:

azdata is working as expected


Running the necessary command line tools for a SQL Server Big Data Cluster in a Docker Container is not that easy, when you know what you have to do. Unfortunately, there was a missing dependency to a shared object file which costed me some time until I found a solution for it.

In one of my next blog postings I will then show you how you can actually deploy a SQL Server Big Data Cluster with this Docker Container. Stay tuned…

Thanks for your time,


It`s your turn
