Summary

This article helps in solving SSL errors that occur while executing curl commands on a third-party URL from Bitbucket cloud pipelines build script.

1 2 3 4 5 6 curl: (60) server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none More details here: http://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.

Diagnosis

  • The issue could have been caused due to an older version of OpenSSL on the docker image

  • Update the open SSL version on your local docker terminal

  • Try to reproduce the issue on local docker using the same image that the pipeline build was running

  • Kindly follow the steps below to locally spin up a docker container and verify if the command is successful
