A simple prerender server
1.2K
A very simple prerender docker container that utilize headless chrome in the background
Download Jessie Frazelle' seccomp profile:
wget https://raw.githubusercontent.com/jfrazelle/dotfiles/master/etc/docker/seccomp/chrome.json -O ~/chrome.json
Run the container:
docker run --name prerender -p '127.0.0.1:3000:3000' --security-opt seccomp=$HOME/chrome.json --restart=always interactivesolutions/prerender
A few things to note, we are binding on 127.0.0.1 which means it's not accessible to remote connections, which is nice, no need for auth. And we also run it with restart always, because well... It's not the most stable project
If the container is failing to start, you can try one of the following
Just make sure the proxy_pass matches the what you have in your run command
location / {
try_files $uri @prerender;
}
location @prerender {
set $prerender 0;
if ($http_user_agent ~* "baiduspider|twitterbot|facebookexternalhit|rogerbot|linkedinbot|embedly|quora link preview|showyoubot|outbrain|pinterest|slackbot|vkShare|W3C_Validator") {
set $prerender 1;
}
if ($args ~ "_escaped_fragment_") {
set $prerender 1;
}
if ($http_user_agent ~ "Prerender") {
set $prerender 0;
}
if ($uri ~ "\.(js|css|xml|less|png|jpg|jpeg|gif|pdf|doc|txt|ico|rss|zip|mp3|rar|exe|wmv|doc|avi|ppt|mpg|mpeg|tif|wav|mov|psd|ai|xls|mp4|m4a|swf|dat|dmg|iso|flv|m4v|torrent|ttf|woff)") {
set $prerender 0;
}
if ($prerender = 1) {
rewrite .* /$scheme://$host$request_uri? break;
proxy_pass http://127.0.0.1:3000;
}
if ($prerender = 0) {
rewrite .* /index.html break;
}
