# 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
|
|
```
|
|
**Please Note:** You should not set a Passphrase (keep it empty) for the private key you generated.
|
|
Because rsync ssh (used for deploy) does not support private key password to be entered as a command line parameter.
|
|
|
|
##### 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

|
```
|
|
- name: Deploy to Staging server

## 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.
|
|
|
|
When opening an issue, please add example of your step with env vars. You can add dummy values.

## 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.
