debian:buster docker 图像上没有安装证书？

Question

I am following these guidelines in a way to find what ca-certificates are out of the box installed on debian:buster docker image.

However it turns out the file with the corresponding information is not there.

▶ docker run -it debian:buster  bash
root@0259e94be9c4:/# awk -v cmd='openssl x509 -noout -subject' '
>     /BEGIN/{close(cmd)};{print | cmd}' < /etc/ssl/certs/ca-certificates.crt
bash: /etc/ssl/certs/ca-certificates.crt: No such file or directory
root@0259e94be9c4:/#

Does debian:buster come with no preinstalled certs at all?

Answer 1

the Package "ca-certificates" is not installed in the docker image you need to install it at first:

apt-get install -y ca-certificates

then you can find the cert in:

/etc/ssl/certs/ca-certificates.crt
