Configuring Harbor with HTTPS Access

Because Harbor does not ship with any certificates, it uses HTTP by default to serve registry requests. However, it is highly recommended that security be enabled for any production environment. Harbor has an Nginx instance as a reverse proxy for all services, you can use the prepare script to configure Nginx to enable https.

In a test or development environment, you may choose to use a self-signed certificate instead of the one from a trusted third-party CA. The followings will show you how to create your own CA, and use your CA to sign a server certificate and a client certificate.

Getting Certificate Authority

openssl genrsa -out ca.key 4096
openssl req -x509 -new -nodes -sha512 -days 3650 \
  -subj "/C=TW/ST=Taipei/L=Taipei/O=example/OU=Personal/" \
  -key ca.key \
  -out ca.crt

Getting Server Certificate

Assuming that your registry’s hostname is, and that its DNS record points to the host where you are running Harbor. In production environment, you first should get a certificate from a CA. In a test or development environment, you can use your own CA. The certificate usually contains a .crt file and a .key file, for example, and

1) Create your own Private Key:

openssl genrsa -out 4096

2) Generate a Certificate Signing Request:

If you use FQDN like to connect your registry host, then you must use as CN (Common Name).

openssl req -sha512 -new \
  -subj "/C=TW/ST=Taipei/L=Taipei/O=example/OU=Personal/" \
  -key \

3) Generate the certificate of your registry host:

Whether you’re using FQDN like or IP to connect your registry host, run this command to generate the certificate of your registry host which comply with Subject Alternative Name (SAN) and x509 v3 extension requirement:

cat > v3.ext <<-EOF
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth 
subjectAltName = @alt_names

openssl x509 -req -sha512 -days 3650 \
  -extfile v3.ext \
  -CA ca.crt -CAkey ca.key -CAcreateserial \
  -in \

Configuration and Installation

1) Configure Server Certificate and Key for Harbor

After obtaining the and files, you can put them into directory such as /root/cert/:

cp /data/cert/
cp /data/cert/
