Introduction

Run the SAS Deployment Wizard to install SAS Studio on a supported Linux 64-bit operating system.   During the installation change the default location for the SAS Studio installation to /opt/SASHome.

mkdir $HOME/SASDocker
cd $HOME/SASDocker

Create a .TAR file that includes the SASHome directory.   The TAR file is required in order to build the Docker image.

tar — cvf SASHomeTar.tar /opt/SASHome

Create a .tar file that includes the SASStudio path.

tar -cvf sasstudio.tar /opt/sas

Create the shell script called sasstudio.sh to start SAS Studio when the container runs.

#! /bin/bash
/opt/SASHome/SASFoundation/9.4/utilities/bin/setuid.sh
/opt/SASHome/sas/studioconfig/sasstudio.sh start
tail -f /dev/null

Dockerfile

Create the Dockerfile.

The first time the docker build command ran with this Dockerfile the container's partition became full,   so reconfigure Docker to work with larger disk partitions.

Remove previously pulled images.

sudo rm -rf /var/lib/docker

Create the Docker Unit file directory.

sudo mkdir /etc/systemd/system/docker.service.d

Pass-in new arguments to the Docker start-up script by including the file docker.conf in the directory above.   Notice the %% at the end of the command option.

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd --storage-opt dm.basesize=50GB --storage-opt dm.min_free_space=50%%

Stop the Docker service.

sudo systemctl stop docker

Returns.

Warning: docker.service changed on disk. Run 'systemctl daemon-reload' to reload units.

Reload Docker configuration file.

sudo systemctl daemon-reload

Start Docker.

sudo systemctl start docker

Another error encountered was:

Step 1/13 : FROM centos:latest
Get https://registry-1.docker.io/v2/: net/http: TLS handshake timeout

To get around this error,   pull the centos:latest image before running the Docker build.

docker pull centos:latest

Returns.

latest: Pulling from library/centos

Build

Build the image.

docker build -t sas4az:v1 .

Run

Run the container.

docker run -d -p 38080:38080 sas4az:v1

Return the container's log file.
