docker nginx proxy server

shared by 張 旭 on 24 Apr 17 - No Cached
  • docker-gen generates reverse proxy configs for nginx and reloads nginx when containers are started and stopped.
  • /var/run/docker.sock:/tmp/docker.sock:ro
  • Use this image to fully support HTTP/2 (including ALPN required by recent Chrome versions).
  • ...10 more annotations...
  • support multiple virtual hosts for a container
  • to connect to your backend using HTTPS instead of HTTP, set VIRTUAL_PROTO=https on the backend container.
  • The contents of /path/to/certs should contain the certificates and private keys for any virtual hosts in use.
  • to replace the default proxy settings for the nginx container, add a configuration file at /etc/nginx/proxy.conf
  • The default configuration blocks the Proxy HTTP request header from being sent to downstream servers
  • add your configuration file under /etc/nginx/conf.d using a name ending in .conf
  • If your container exposes multiple ports, nginx-proxy will default to the service running on port 80. If you need to specify a different port, you can set a VIRTUAL_PORT env var to select a different one.
  • To add settings on a per-VIRTUAL_HOST basis, add your configuration file under /etc/nginx/vhost.d
  • SNI
  • The default behavior for the proxy when port 80 and 443 are exposed is as follows: If a container has a usable cert, port 80 will redirect to 443 for that container so that HTTPS is always preferred when available. If the container does not have a usable cert, a 503 will be returned.

javascript jwt authorization authentication oauth security

shared by 張 旭 on 24 Apr 18 - No Cached
  • a stateless authentication mechanism as the user state is never saved in server memory
  • In authentication, when the user successfully logs in using their credentials, a JSON Web Token will be returned and must be saved locally (typically in local storage, but cookies can be also used), instead of the traditional approach of creating a session in the server and returning a cookie.
  • ser agent should send the JWT, typically in the Authorization header using the Bearer schema.
  • ...2 more annotations...
  • It doesn't matter which domains are serving your APIs, so Cross-Origin Resource Sharing (CORS) won't be an issue as it doesn't use cookies.
  • WT and SAML tokens can use a public/private key pair in the form of a X.509 certificate for signing.

system monitor php go

shared by 張 旭 on 23 Apr 18 - No Cached
  • Zabbix has core written in C and webUI based on PHP
  • Zabbix stores data in RDBMS (MySQL, PostgreSQL, Oracle, sqlite) of user's choice.
  • Prometheus uses its own database embedded into backend process
  • ...8 more annotations...
  • Zabbix by default uses "pull" model when a server connects to agents on each monitoring machine, agents periodically gather the info and send it to a server.
  • Prometheus prefers "pull" model when a server gather info from client machines.
  • Prometheus requires an application to be instrumented with Prometheus client library (available in different programming languages) for preparing metrics.
  • expose metrics for Prometheus (similar to "agents" for Zabbix)
  • Zabbix uses its own tcp-based communication protocol between agents and a server.
  • Prometheus uses HTTP with protocol buffers (+ text format for ease of use with curl).
  • Prometheus offers basic tool for exploring gathered data and visualizing it in simple graphs on its native server and also offers a minimal dashboard builder PromDash. But Prometheus is and is designed to be supported by modern visualizing tools like Grafana.
  • Prometheus offers solution for alerting that is separated from its core into Alertmanager application.
