Callable requires a multi-step installation procedure to get the solution running.
Obtain a license
At first you need to register on this site to obtain a license.
The sign up process is completed by an welcome email which will contain your license key and various links on how to get started.
Obtain SAP JCO
The SAP JCO can be downloaded from https://support.sap.com/en/product/connectors/jco.html.
For Callable you need to download the “Linux (for Intel compatible processors)” version in 64-bit x86 of the JCO.
The downloaded zip file is then needed for the creation of the external volume for the docker container.
Prepare JCO in local directory
Extract the downloaded JCO into a local directory.
Start the Container
run the following command:
docker run \ -p 8080:8080 \ -e license=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \ -v "$(pwd)"/sapjco3-linuxx86_64-3.0.18:/opt/callable/lib \ -e jco__client__ashost=host.example.com \ -e jco__client__client=000 \ -e jco__client__passwd=secret1 \ -e jco__client__sysnr=00 \ -e jco__client__user=user1 \ -e jco__destination__pool_capacity=10 \ -e jco__client__lang=en \ gcr.io/openapi4sap/callable
