ca certificates


old php container says : curl: (60) SSL certificate problem: certificate has expired

Since 1 or 2 days my old php container (dockerhub php:5.4-apache) can't use curl anymore. this is the log when running curl inside this container.

$> docker run --rm -ti php:5.6-apache bash
$> curl -X POST
curl: (60) SSL certificate problem: certificate has expired
More details here:

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
This same call works on a modern (updated) OS.

the reason is cacerts of the os are outdated

To update them you need to do the following

RUN sed -i 's/mozilla\/DST_Root_CA_X3.crt/!mozilla\/DST_Root_CA_X3.crt/g' /etc/ca-certificates.conf && update-ca-certificates

or the other not really working solution :

curl -k > cacert.pem
# works : curl --cacert cacert.pem -X POST

apt-get install ca-certificates
openssl x509 -outform der -in cacert.pem -out cacert.crt
cp cacert.crt /usr/local/share/ca-certificates/
