Add swap memory with ansible

Question

I\'m working on a project where having swap memory on my servers is a needed to avoid some python long running processes to go out of memory and realized for the first time that

Answer 1

Here is the ansible-swap playbook that I use to install 4GB (or whatever I configure group_vars for dd_bs_size_mb * swap_count) of swap space on new servers:

I also added a function in my ~/.bash_profile to help with the task:

# Path to where you clone the repo
ANSIBLE_SWAP_PLAYBOOK=$HOME/dev/ansible-swap

install-swap ()
{
    usage='Usage: install-swap HOST';
    if [ $# -ne 1 ]; then
        echo "$usage";
        return 1;
    fi;
    ansible-playbook $ANSIBLE_SWAP_PLAYBOOK/ansible-swap/site.yml --extra-vars "target=$1"
}

Just make sure to add your HOST to your ansible inventory first.

Then it's just install-swap HOST.
