docker: 'stack' is not a docker command.

While deploying the docker services using stack deploy command. We got following error.

docker stack deploy -c docker-compose.yml appslab
docker: 'stack' is not a docker command.
See 'docker --help'.

Resolution
Upgrade docker to 1.13

In Centos 7 we used the following to get the docker upgraded. Now the docket-latest package in centos7 is upgraded to 1.13

wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-1.13.1-1.el7.centos.x86_64.rpm

wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-selinux-1.13.1-1.el7.centos.noarch.rpm

#package for docker-engine-selinux
yum install -y policycoreutils-python
rpm -i docker-engine-selinux-1.13.1-1.el7.centos.noarch.rpm

#package for docker-engine
yum install -y libtool-ltdl libseccomp
rpm -i docker-engine-1.13.1-1.el7.centos.x86_64.rpm

#remove rpm packages
rm docker-engine-* -f

#enable systemd service
systemctl enable docker

#start docker
systemctl start docker
