Juju 1.24.0 has initial support for CentOS as a deployment OS (the Juju client
software is already supported on CentOS - see the

ready to be used and tested.
CentOS should be deployable on any cloud that supports
cloud-init in it's

mkdir local juju sync-tools --local-dir local cp -r local/tools <path/to/webserver>

yumin the environment configuration. The values that you specify for
aptpackages will be used for
yumpackages as well. This limitation will be fixed as soon as possible.
