Imagik

Pyazo, but fast. Imagik is a fast and lightweight fileserver, that

• lets you access files by path
• lets you access files by their Hash (MD5/SHA1/SHA2/SHA512)
• lets you upload files with a very simple API

Running

Docker

Run the container like this:

docker run -p 8000:8000 -v "whatever directory you want to share":/share ghcr.io/beryju/imagik

Now you can access imagik on http://localhost:8000

Binary

Download a binary from GitHub and run it:

./imagik

Now you can access imagik on http://localhost:8000

Configuration

Example config file:

---
# secretKey: # Set this to the output of ./imagik generate-key
listen: localhost:8000
rootDir: ./root
authDriver: static # or null for no authentication or oidc
authStaticConfig:
  tokens:
    # Key is the username
    # Value is password hash generated by ./imagik hash-password
    test: "|2a|10|TanDKWLYO3LUS3SEyQGTz.L51M6cSJsLsK0wVEWl5lIK1XucTBQ8u" # test
# authOIDCConfig:
#   url: provider URL, which has a .well-known/openid-configuration
#   clientID: some-client-id
#   clientSecret: some-client-secret
#   redirect: URL which should be sent as redirect, /api/pub/oidc/callback
#   provider: Name of the login button

API

GET /<path>

Retrieve file stored at path.

GET /<path>?meta

Retrieve metadata for file stored at path.

PUT /<path>

Requires authentication

Accepts file uploads from the HTTP Request body, like using curl --data "@/path/to/filename". Returns a JSON object with all the hashes,

{
    "SHA128":"acd5aeeb3c8d1cf580a59bc3e125d249ecdd0eda",
    "SHA256":"e6b104c1420af07013b4378ddacaaa3938259422f07d5d47f7ea114cf9de80cf",
    "SHA512":"10c08e2134fb953f891c2a3655f3744c0321fa72aefdf6bff000eff0a3f7882a008fff477dfec9aa22519ad17fb0fafd602caf3773cb848a5250131fdf8559ab",
    "SHA512Short":"10c08e2134fb953f",
    "MD5":"7e97fa079923fcdb39eb39b480729f36"
}

GET /api/pub/health/liveness

Healthcheck endpoint, which returns a 201 Response as soon as imagik is running.

GET /api/pub/health/readiness

Healthcheck Readiness probe, which returns a 201 after the Hash Map has been populated, otherwise a 500.

GET /api/priv/list[?pathOffset=]

Requires authentication

List contents of a directory. Accepts a query parameter pathOffset, which is appended to the root directory.

POST /api/priv/move?to=&from=

Requires authentication

Move a file. Requires two query parameters, from and to, which are relative to the root directory.

POST /api/priv/upload

Requires authentication

Accepts Multipart-Form Encoded files and uploads them to the respective path from the form relative to the root directory.

Migrating from pyazo

If you didn't use Collections in pyazo, you can simple re-use the same Media folder for imagik, and all URLs will continue to work.

If you did use Collections, use the script below, to mirror your Collection Structure into Filesystem folders, which are used by imagik.

# Execute this in your pyazo installation directory
# docker-compose exec server ./manage.py shell
# Then paste the contents below into the shell.
# This will output the commands required to move the files
# into folders.
from pyazo.core.models import *
for c in Collection.objects.all():
    print(f"mkdir {c.name}")
    for o in c.object_set.all():
        rel_path = o.file.path.replace('/app/media/', '')
        print(f"mv {rel_path} {c.name}/{rel_path}")
