在Linux中新增CA证书

$> cp xxx.crt /usr/local/share/ca-certificates/xxx.crt
$> update-ca-certificates
最后检查下面文件最后是否包含新增证书
/etc/ssl/certs/ca-certificates.crt
or
/etc/ca-certificates.conf

Docker:

FROM alpine

COPY Letsencrypt_Root_CA.crt /usr/local/share/ca-certificates/
RUN apk --no-cache add ca-certificates \
  && rm -rf /var/cache/apk/* \
  && update-ca-certificates
