seaweedfs webp convert service

---

中文文档

Based on docker with golang expand seaweedfs implementation convert to webp images

Docker

build

There are two ways to construct it, either way.

pull from docker hub

docker pull yhan219/seaweedfs-webp:lastest

build with dockerfile

docker build -t yhan219/seaweedfs-webp:1.0 .

run

docker run -d --name seaweedfs-webp -e volumeServer="http://ip:8080" -p 18080:80 yhan219/seaweedfs-webp:1.0

the param volumeServer is seaweedfs volume url

Usage

The service listens on port 18080 for GET requests on the path end with .webp. Any other path suffix, returns a 404 not found status. And then you just need add .webp suffix with your image url.Optional,add a list of key-value request params that are passed on to the appropriate cwebp binary. Boolean values are interpreted as flag arguments (e.g.: -nostrong).

Sample

image url is:

http://ip:8080/file/96,0c6b879ca3780c

then webp url is:

http://ip:18080/file/96,0c6b879ca3780c.webp

add convert param,eg:

http://ip:18080/file/96,0c6b879ca3780c.webp?q=1&nostrong=true&z=5

will have the effect of the following command-line being executed on the server:

cwebp -q 1 -nostrong -z 5 -o - -- -

Advanced

In general, nginx works better in combination.

• docker build -t yhan219/seaweedfs-webp:1.0 .
• docker run -d --name seaweedfs-webp -e volumeServer="http://www.xxx.com" -p 18080:80 yhan219/seaweedfs-webp:1.0

nginx config eg:

serer {
    listen 80;
    server_name www.xxx.com;
    ## ...
    location /file/ {
         proxy_pass http://localhost:8080/;
    }
    location ~* \.webp$ {
                    ## cache
                    proxy_pass http://localhost:18080/;
            }
}

now image url is:

http://www.xxx.com/file/96,0c6b879ca3780c

and webp url is:

http://www.xxx.com/file/96,0c6b879ca3780c.webp
