旧 php 容器说：curl: (60) SSL 证书问题：证书已过期

Question

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 https://xxxxx.com
curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

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.

Answer 1

the reason is cacerts of the os are outdated

To update them you need to do the following

curl -k https://curl.se/ca/cacert.pem > cacert.pem
# works : curl --cacert cacert.pem -X POST https://xxxxx.com

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

other option:

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

best option (imho):

apt-get update
apt-get upgrade -y

Answer 2

Raphael's answer is somewhat correct. I checked the https://curl.se/ca/cacert.pem file and found that as of today it contains the Digital Signature Trust Co. (DST Root CA X3) CA Root certificate. So replacing your Root CA certificate bundle may not be the answer, if it contains the same expired certificate.

It doesn't get clear what cacert you're using. Can you share?

You didn't mention what OS is that, so I would assume Linux.

You can isolate your OS CA Root certificate location and check, if one of your expired certificates is the cause.

The steps in this article are the same for any expired CA Root certificate in the CA Root bundle (eg https://curl.se/ca/cacert.pem ) cert chain. https://stackoverflow.com/a/69411107/1549092
