How to add a certificate to docker

1. Upgrade process: sudo apt-get update

Problems such as missing packages and old package versions can be solved in this way. If not, then it means that authentication is missing and you need to generate your own authentication certificate.

2. Generate your own authentication certificate

Create a folder first

mkdir -p certs

After that, create the certificate. The certificate is generated in the folder just created.

openssl req -newkey rsa:4096 -nodes -sha256 -keyout /root/certs/domain.key -x509 -days 365 -out /root/certs/domain.crt

Then put the certificate generated by certs in the /etc/docker/ directory

Then restart the docker service sudo service docker restart

After reboot

Supplement: Configure HTTPS certificate using nginx installed with Docker

Create a new ssl.conf and put the file in the conf.d folder

server {
  listen 443;
  server_name localhost;
  ssl on;
  root html;
  index index.html index.htm;
  ssl_certificate cert/1533224843981.pem;
  ssl_certificate_key cert/1533224843981.key;
  ssl_session_timeout 5m;
  ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  location / {
   root html;
   index index.html index.htm;
  }
 }

Note: cert is a relative path. If it is a Linux folder, it is in the nginx.conf folder. If it is a Windows folder, it is in the conf folder.

run

 docker run --name mynginx -p 443:443 -v /opt/data/nginx/nginx.conf:/etc/nginx/nginx.conf
 -v /opt/data/nginx/conf.d:/etc/nginx/conf.d/default.conf 
-v /opt/data/nginx/www:/www -v /opt/data/nginx/cert:/etc/nginx/cert 
-v /opt/data/nginx/ssl.conf:/etc/nginx/conf.d/ssl.conf -d nginx
