Docker install on Azure

I have installed Docker CE on an Azure resource group. When I run docker-compose to create the Xibo instance, I get the following error:

Starting xibodocker_cms-xmr_1 …
Starting xibodocker_cms-db_1 …
libgcc_s.so.1 must be installed for pthread_cancel to work
Aborted

How can I correctly install the missing component?

Are you perhaps using a 32 bit virtual machine? Our Docker images are 64 bit only.

I don’t thinks so:

Welcome to Docker!
swarm-manager000000:~$ uname -a
Linux swarm-manager000000 4.9.81-moby #1 SMP Thu Mar 22 18:46:05 UTC 2018 x86_64 Linux

Are you using swarm? The compose files we ship aren’t setup for swarm

Yes, I was using swarm. I have abandoned that and just spun up a vanilla Ubuntu VM and successfully installed Docker and Xibo on it.

I think you could perhaps update your documentation to mention Azure and specifically to do what I did rather than using the standard Docker-on-Azure package available on the Azure Marketplace.
