Driver Docker missing ulimits #1091
Description
Feature request
Allow molecule to set ulimit values for the Docker Driver.
Molecule and Ansible details
ansible --version
ansible 2.4.2.0
config file = None
configured module search path = [u'/Users/yf30lg/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/local/lib/python2.7/site-packages/ansible
executable location = /Users/yf30lg/Library/Python/2.7/bin/ansible
python version = 2.7.14 (default, Sep 25 2017, 09:53:22) [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.37)]
molecule --version
molecule, version 2.6.0
- Molecule installation method: pip
- Ansible installation method: pip
Desired Behaviour
In some cases it may be required to set a different ulimit for a Docker instance. For example "nofile". The Ansible module Docker Container allows this using the list "ulimits".
I'll prepare a merge request and link it to this feature request.
A hint of what work on my laptop now:
molecule.yml:
...
- name: release-centos-6
image: centos:6
ulimits:
- nofile:262144:262144
...
create.yml:
- name: Create molecule instance(s)
docker_container:
...
ulimits: "{{ item.ulimits | default(omit) }}"
with_items: "{{ molecule_yml.platforms }}"
