Installation
Docker
It is highly recommended that you use the official Docker image to run Pastey. To do so, simply run:
$ docker run -d -p 5000:5000 -v /path/to/local/dir:/app/data cesura/pastey:latest
Change /path/to/local/dir to a local folder you would like to use for persistent paste storage. It will be mounted in the container at /app/data.
Pastey will then be accessible at http://localhost:5000
Docker (non-AVX processor)
If your processor does not have support for AVX instructions, the "latest" image will fail to run. This is due to a decision by Tensorflow to enable this compile flag by default in version 1.5+. However, Anaconda's distribution of Tensorflow supports older architectures even in the 2.x line. You can instead use the image tagged latest-conda:
$ docker run -d -p 5000:5000 -v /path/to/local/dir:/app/data cesura/pastey:latest-conda
docker-compose
If you prefer to use docker-compose:
$ wget https://raw.githubusercontent.com/Cesura/pastey/main/docker-compose.yml && docker-compose up -d
Note that this must be modified if you wish to use a local directory for storage, rather than a Docker volume.
Local
With language detection
Requirements:
- Python 3.8
- AVX-enabled processor (or a Python environment configured to use Anaconda's Tensorflow)
$ git clone https://github.com/Cesura/pastey.git && cd pastey && mkdir ./data
$ pip3 install -r requirements.txt
$ python3 app.py
Without language detection
If you prefer to not use the language detection feature, use the included patch_no_tensorflow.sh script to remove the guesslang requirements:
$ git clone https://github.com/Cesura/pastey.git && cd pastey && mkdir ./data
$ ./patch_no_tensorflow.sh && pip3 install -r requirements.txt
$ python3 app.py
Configuration
Here is a list of the available configuration options:
| Environment Variable | config.py Variable | Description | Default Value |
|---|---|---|---|
| PASTEY_DATA_DIRECTORY | data_directory | Local directory for paste storage | ./data |
| PASTEY_LISTEN_ADDRESS | listen_address | Address to listen on | 0.0.0.0 |
| PASTEY_LISTEN_PORT | listen_port | Port to listen on | 5000 |
| PASTEY_USE_WHITELIST | use_whitelist | Enable/disable whitelisting for admin tasks (view recent, delete, config) | True |
| PASTEY_WHITELIST_CIDR | whitelist_cidr | List of whitelisted IP addresses or networks (in CIDR format). When passed as an environment variable, it should be a comma-separated list. | [ '127.0.0.1/32' , '10.0.0.0/8' , '172.16.0.0/12' , '192.168.0.0/16' ] |
| PASTEY_BLACKLIST_CIDR | blacklist_cidr | List of blocked IP addresses or networks (in CIDR format). When passed as an environment variable, it should be a comma-separated list. | [] |
| PASTEY_RESTRICT_PASTING | restrict_pasting | Enable/disable restricting of pasting to whitelisted users | False |
| PASTEY_RATE_LIMIT | rate_limit | Rate limit for pasting, for non-whitelisted users | 5/hour |
| PASTEY_GUESS_THRESHOLD | guess_threshold | Threshold for automatic language detection guesses. If a result is below this value, it is treated as Plaintext. | 0.20 |
| PASTEY_RECENT_PASTES | recent_pastes | Number of recent pastes to show on the home page | 10 |
| PASTEY_BEHIND_PROXY | behind_proxy | Inform Pastey if it is behind a reverse proxy (nginx, etc.). If this is the case, it will rely on HTTP headers X-Real-IP or X-Forwarded-For. NOTE: Make sure your proxy config sets these values | False |
| PASTEY_DEFAULT_THEME | default_theme | Select which theme Pastey should use by default. This is overridden by client options. | Light |
| PASTEY_PURGE_INTERVAL | purge_interval | Purge interval (in seconds) for checking expired pastes in background thread | 3600 |
| PASTEY_FORCE_SHOW_RECENT | force_show_recent | Show recent pastes on the home page, even to non-whitelisted users (without delete button) | False |
| PASTEY_IGNORE_GUESS | ignore_guess | Ignore these classifications for language detection | ['TeX', 'SQL'] |
| PASTEY_SHOW_CLI_BUTTON | show_cli_button | Enable/disabling showing of CLI button on home page | True |
Docker configuration
For Docker environments, it is recommended that the options be passed to the container on startup:
$ docker run -d -p 5000:5000 -e PASTEY_LISTEN_PORT=80 -e PASTEY_BEHIND_PROXY="True" cesura/pastey:latest
