# ssh deployments
Deploy code with rsync over ssh.
Execute remote scripts before or after rsync
NodeJS version is more than a minute `faster` than simple Docker version.
This GitHub Action deploys specific directory from `GITHUB_WORKSPACE` to a folder on a server via rsync over ssh, using NodeJS.
This action would usually follow a build/test action which leaves deployable code in `GITHUB_WORKSPACE`, eg `dist`;
In addition to rsync, this action provides scripts execution on remote host before and/or after rsync.
# Configuration
Pass configuration with `env` vars
##### 1. `SSH_PRIVATE_KEY` [required]
Private key part of an SSH key pair.
The public key part should be added to the `authorized_keys` file on the server that receives the deployment.
More info for SSH keys: https://www.ssh.com/ssh/public-key-authentication
The keys should be generated using the PEM format. You can use this command
```
ssh-keygen -m PEM -t rsa -b 4096
```
##### 2. `REMOTE_HOST` [required]
eg: mydomain.com
##### 3. `REMOTE_USER` [required]
eg: myusername
##### 4. `REMOTE_PORT` (optional, default '22')
eg: '59184'
##### 5. `ARGS` (optional, default '-rlgoDzvc -i')
For any initial/required rsync flags, eg: `-avzr --delete`
##### 6. `SOURCE` (optional, default '')
The source directory, path relative to `$GITHUB_WORKSPACE` root, eg: `dist/`.
Multiple sources should be separated by space.
##### 7. `TARGET` (optional, default '/home/REMOTE_USER/')
The target directory
##### 8. `EXCLUDE` (optional, default '')
path to exclude separated by `,`, ie: `/dist/, /node_modules/`
##### 9. `SCRIPT_BEFORE` (optional, default '')
Script to run on host machine before rsync. Single line or multiline commands.
Execution is preformed by storing commands in `.sh` file and executing it via `.bash` over `ssh`
If you have issues with `ssh` connection, use this var, eg `SCRIPT_BEFORE: ls`.
This will force `known_hosts` update, adding your host via `ssh-keyscan`.
##### 10. `SCRIPT_AFTER` (optional, default '')
Script to run on host machine after rsync.
Rsync output is stored in `$RSYNC_STDOUT` env variable.
##### 11. `SSH_CMD_ARGS` (optional, default '-o StrictHostKeyChecking=no')
A list of ssh arguments, they must be prefixed with -o and separated by a comma, for example: -o SomeArgument=no, -o SomeOtherArgument=5
# Usage
Use the latest version from Marketplace,eg: ssh-deploy@v2
or use the latest version from a branch, eg: ssh-deploy@main
```
- name: Deploy to Staging server
uses: easingthemes/ssh-deploy@main
env:
SSH_PRIVATE_KEY: ${{ secrets.SSH_PRIVATE_KEY }}
ARGS: "-rlgoDzvc -i"
SOURCE: "dist/"
REMOTE_HOST: ${{ secrets.REMOTE_HOST }}
REMOTE_USER: ${{ secrets.REMOTE_USER }}
TARGET: ${{ secrets.REMOTE_TARGET }}
EXCLUDE: "/dist/, /node_modules/"
SCRIPT_BEFORE: |
whoami
ls -al
SCRIPT_AFTER: |
whoami
ls -al
echo $RSYNC_STDOUT
```

## Issues
This is a GitHub Action wrapping `rsync` via `ssh`. Only issues with action functionality can be fixed here.
Almost 95% of the issues are related to wrong SSH connection or `rsync` params and permissions.
These issues are not related to the action itself.
- Check manually your ssh connection from your client before opening a bug report.
- Check `rsync` params for your use-case. Default params are not going to be enough wor everyone, it highly depends on your setup.
- Check manually your rsync command from your client before opening a bug report.
I've added e2e test for this action.
Real example is executed on every PR merge to `main`.
Check actions tab for example.

## Tips
- Optional ENV variables are created for simple requirements.
For complex use cases, use `ARGS` and `SSH_CMD_ARGS` to fully configure `rsync` with all possible options.
- If you need to use multiple steps, eg multi targets deployment, save shared ENV variables in `>> $GITHUB_ENV`.
Check .github/workflows/e2e.yml for an example
- For multi sources, use -R ARG to manipulate folders structure.

## Disclaimer
Check your keys. Check your deployment paths. And use at your own risk.
