- Every time that I do a clean install on my machine it takes a few hours till I - get to point where I was before formatting it, install all packages, select - themes, icons, fonts, install IDEs, extensions and so on. After doing it a few - times I came to the conclusion that I would save time by spending time - automating this chore, and as a result, I could tinker a little more with my - system and not worry about spending a weekend re-installing everything (which - have happened more time that I'd like to remember). -

-

- So after a few attempts using python and bash I ended with many files and - keep everything organized and concise turned out to be more tedious than the - setup itself. So there comes Ansible. - It is an enterprise-graded software used to automate tasks. It has A LOT OF - features and it can be really helpful if you're a sysadmin but for now we're - going to focuson - - Ansible Pull - - and - - Playbooks - . As better described: -

- [Ansible-Pull] is used to up a remote copy of ansible on each managed - node, each set to run via cron and update playbook source via a source - repository. This inverts the default push architecture of Ansible into a - pull architecture, which has near-limitless scaling potential. - - Playbooks are Ansible’s configuration, deployment, and orchestration - language. They can describe a policy you want your remote systems to - enforce, or a set of steps in a general IT process. - (source) -
-

-

- The goal is to pull and run a playbook remotely using a git repository. The - playbook will describe the tasks needed to setup our machine from scratch. -
- But first lets tinker a bit a with playbooks locally with ansible-playbook, - to do so we need to add localhost to ansible's hosts list. Add it to - /etc/ansible/hosts: -

[all]
-localhost
-

-

- As an experiment we're going to write a asks to install vim. Currently, I'm - using Fedora thus we going to use dnf modeule to install packages, but if - you're using another distribution look for a equivalent module like apt - module for Ubuntu. - - The playbook to install is quite simple: - -

# main.yaml
-- hosts: all
-  tasks:
-     - name: install vim
-       dnf:
-         name: vim
-         state: latest
-
-
host
-
it is required and it has to match our hosts otherwise the playbook won't run.
-
taks
-
- it is the list of tasks that the playbook will perform, in this case - will be dnf install vim. -
-
-

-

- To run a playbook use the command ansible-playbook commando to run main.yml - direct from disk, do to so just run the following command: -

sudo ansible-playbook --connection=local main.yml
-

-

- After a few seconds, vim will be installed on your machine. -

PLAY [all] *************************************************************
-
-TASK [Gathering Facts] *************************************************
-ok: [localhost]
-
-TASK [install vim] *****************************************************
-ok: [localhost]
-
-PLAY RECAP *************************************************************
-localhost                  : ok=2    changed=0    unreachable=0    failed=0
-

-

- This is the first step, next part we shall create a more complex playbook and - setup repository to run it remotely using ansible-pull. -

- See part 1 -

- Now we're going to setup ansible to work with a git repository. The process is - quite similar to ansible-playbook, the only difference is that the source for - the playbook will be a remote repository and not a local file. Following the - previous example we'll get vim setup automated. -

-

- Create a git repository wherever you see - fit, gitlab - and github offer free repositories. For - this task we need to add only two file: one for the yml file describing the - tasks and the .vimrc file. -

-

- In the .vimrc add your own configuration, you can see - mine - - over here - , it is pretty simple as I don't use it but for simple text editing - (like this post) so you can start with that if you don't have one. -

-

- The yml file will have two tasks, one is to install vim, just like we did in the part 1. -

# main.yml
----
-- name: install vim
-  dnf:
-    name: vim
-    state: latest
-

-

- To copy .vimrc file to your $HOME we going to - use copy - module: -

-

- After we've added those two files to repository you will have be something - - like this. - -
- Parms: -

-

-

- Remember man is your best friend, take a look at man ansible-pull to know - more about its parameters. -

-

- The best part you can quickly test and see the result by running my sample: -

ansible-pull \
-    -U https://gitlab.com/gabrielgio/homestation.git \
-    -C debcf3458df511aef9f7dca0cb73f6cf6baddd5d \
-    -i all \
-    main.yml
-

-

- The idea here is to keep your repository as a source of truth when comes to - configuration, you can add ansible-pull to a CRON tab, so you just need to - push something to your repository and after a few minutes not only your - machine but all the machines that have it setup will run the playbooks. You - can use this method as a simple way to install software, update machines or - even distribute tooling company-wise. -

- By default K3S comes only - with local-path - storage class, and if you are running with more than one node in your - cluster you may want to use a more “distributed” solution. - For may case I opted for NFS. -

-

- To check the current storage class you can run: -

- 
k3s kubectl get storageclasses

- To start adding First you need to - install helm on your server. - To do so you may run: -

curl -sSL https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | bash
-

- Be careful when running scripts directly into bash always check the - source Sometimes is also recommended to do not pipe directly to bash -

-

- Once it is installed we need to add - the NFS - storage classes. It has two providers, I have - chose NFS - Subdir External Provisioner. -

-

- Add the helm repo -

- - 
helm repo add nfs-subdir-external-provisioner https://kubernetes-sigs.github.io/nfs-subdir-external-provisioner/
-

- Then we need to actually install the provider -

-
-
helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner
---set nfs.server=x.x.x.x
---set nfs.path=/exported/path

-

- Set the nfs.server and nfs.path accordingly - with your setup. -

- After that if we run k3s kubectl get storageclasses it will - now print another NFS provider: -

- This is based on Log in to - Docker Hub. It is just a bit different to use podman. -

-

- First we should take a look at podman-login man page: -

man podman login
-

-

- It will give some valueable information like the location of auth.json file. Now we can login using podman: -

podman login registry.gitlab.com
-

-

Then check the auth.json file located at ${XDG_RUNTIME_DIR}/containers/auth.json (as described - by the manual). It will contain your auth config: -

{
-	"auths": {
-		"registry.gitlab.com": {
-			"auth": "..."
-		}
-	}
-}
-

-

- Now copy that file over to the server and register it in k8s with the following command: -


-kubectl create secret generic regcred \
-    --from-file=.dockerconfigjson=auth.json \
-    --type=kubernetes.io/dockerconfigjson
-

-

- Once you have created you can list by kubectl get secret: -
