Setup custom certificates

You can use your own certificates with EasyHAProxy. You just need to let EasyHAProxy know that certificate.

There are two ways to do that.

• Setup certificate as a label definition in docker container
• Map the certificate as a docker volume

Setup certificate as a label definition in docker container

1. Create a single PEM from the certificate and key.

cat example.com.crt example.com.key > single.pem

cat single.pem

-----BEGIN CERTIFICATE-----
MIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKYwggSiAgEAAoIBAQC5ZheHqmBnEJP+
U9r1gxYWKLzdqrMrcxtQN6M1hIH9n0peuJeIrybdcV7sMbStMXI=
-----END CERTIFICATE-----

-----BEGIN PRIVATE KEY-----
MIIEojCCA4qgAwIBAgIUegW2BimwuL4RzRZ2WYkHA6U5nkAwDQYJKoZIhvcNAQEL
3j4wz8/I5fdsk090j4s5KA==
-----END PRIVATE KEY-----

2. Convert the single.pem to BASE64 in a single line:

cat single.pem | base64 -w0

3. Define a label in yout container

Add the Base64 string you generated before to the label easyhaproxy.[definition].sslcert

Map the certificate as a docker volume

EasyHAProxy stores the certificates inside the container folder /certs/haproxy.

1. Run EasyHAProxy with the volume for the certificates:

docker volume create certs_haproxy

docker run \
    /* other parameters */
    -v certs_haproxy:/certs/haproxy \
    -d byjg/easy-haproxy

2. Create a single PEM from the certificate and the key.

cat example.com.crt example.com.key > single.pem

cat single.pem

-----BEGIN CERTIFICATE-----
MIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKYwggSiAgEAAoIBAQC5ZheHqmBnEJP+
U9r1gxYWKLzdqrMrcxtQN6M1hIH9n0peuJeIrybdcV7sMbStMXI=
-----END CERTIFICATE-----

-----BEGIN PRIVATE KEY-----
MIIEojCCA4qgAwIBAgIUegW2BimwuL4RzRZ2WYkHA6U5nkAwDQYJKoZIhvcNAQEL
3j4wz8/I5fdsk090j4s5KA==
-----END PRIVATE KEY-----

3. Copy this certificate to EasyHAProxy volume

docker cp single.pem easyhaproxy:/certs/haproxy
