# Fetchit
The purpose of FetchIt is to allow for GitOps management of podman managed containers.
This project is currently under development. For a more detailed explanation of the project visit the docs page.
https://fetchit.readthedocs.io/
A quickstart example is available at https://github.com/containers/fetchit/blob/main/docs/quick_start.rst
## Developing
To develop and test changes of FetchIt, the FetchIt image can be built locally and then run on the development system.
```
go mod tidy
go mod vendor
podman build . --file Dockerfile --tag quay.io/fetchit/fetchit-amd:latest
podman tag quay.io/fetchit/fetchit-amd:latest quay.io/fetchit/fetchit:latest
```
Once the image has been successfully built the image can be ran using the following command.
```
podman run -d --rm --name fetchit --security-opt label=disable -v fetchit-volume:/opt -v ./examples/readme-config.yaml:/opt/config.yaml -v /run/user/$(id -u)/podman//podman.sock:/run/podman/podman.sock quay.io/fetchit/fetchit:latest
```
## Running
FetchIt requires the podman socket to be running on the host. The socket can be enabled for a specific user or for root.
To enable the socket for $USER:
```
systemctl --user enable podman.socket --now
```
To enable the socket for root:
```
systemctl enable podman.socket --now
```
#### Verify running containers before deploying fetchit.
```
podman ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
```
### FetchIt launch options
FetchIt and can be started manually or launched via systemd.
Define the parameters in your `$HOME/.fetchit/config.yaml` to relate to your git repository.
This example can be found in [./examples/readme-config.yaml](examples/readme-config.yaml)
```
targetConfigs:
- url: https://github.com/containers/fetchit
branch: main
fileTransfer:
- name: ft-ex
targetPath: examples/fileTransfer
destinationDirectory: /tmp
schedule: "*/1 * * * *"
raw:
- name: raw-ex
targetPath: examples/raw
schedule: "*/1 * * * *"
```
#### Launch using systemd
Two systemd files are provided to allow for FetchIt to run as a user or as root. The files are under the systemd folder, differentiated by fetchit-root and fetchit-user.
Ensure that there is a config at `$HOME/.fetchit/config.yaml` before attempting to start the service.
For root
```
cp systemd/fetchit-root.service /etc/systemd/system/fetchit.service
systemctl enable fetchit --now
```
For $USER
```
mkdir -p ~/.config/systemd/user/
cp systemd/fetchit-user.service ~/.config/systemd/user/fetchit.service
systemctl --user enable fetchit --now
```
#### Manually launch the fetchit container using a podman volume
```
podman run -d --rm --name fetchit \
-v fetchit-volume:/opt \
-v $HOME/.fetchit:/opt/mount \
-v /run/user/$(id -u)/podman//podman.sock:/run/podman/podman.sock \
--security-opt label=disable \
quay.io/fetchit/fetchit:latest
```
**NOTE:**
* If a podman volume is not the preferred storage solution a directory can be used as well.
An example would be `-v ~/fetchit-volume:/opt` instead of `-v fetchit-volume:/opt`.
* For filetransfer, the `destination directory must exist` on the host.
The container will be started and will run in the background. To view the logs:
```
podman logs -f fetchit
git clone https://github.com/containers/fetchit main --recursive
