'composer install' command fails on Docker giving 'SSL Operation Failed with code 1' error

Question

I am on the Windows machine, with Docker running. Docker image is FROM php:7.3-apache.

with

System : Linux b6df004de9df 4.9.184-linuxkit #1 SMP Tue Jul 2 22:58:16 UTC 2019 x86_64

having Composer installed in this container successfully with Composer version 1.9.0 2019-08-02 20:55:32.

Now, I entered into the bash of the container and entered a command $ composer init which run successfully and initialized the composer, however, upon $ composer install command, it gives an error

[Composer\Downloader\TransportException] The "https://repo.packagist.org/packages.json" file could not be downloaded: SSL operation failed with code 1. Open SSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed
Failed to enable crypto failed to open stream: operation failed

As I could see its an OpenSSL error for Certificate, I tried to get exact error :

root@b6df004de9df:/var/www/html/my_JSON_proj# openssl s_client -connect www.google.com:443 CONNECTED(00000003) depth=2 C = US, ST = California, O = Zscaler Inc., OU = Zscaler Inc., CN = Zscaler Intermediate Root CA (zscalertwo.net) , emailAddress = [email protected] verify error:num=20:unable to get local issuer certificate

To re-confirm, I again tried :

root@b6df004de9df:/var/www/html/my_JSON_proj# curl https://google.com curl: (60) SSL certificate problem: unable to get local issuer certificate

Openssl Version: OpenSSL 1.1.0k 28 May 2019

Output of openssl_get_cert_locations() :

array(8) {
["default_cert_file"]=> "/usr/lib/ssl/cert.pem"
["default_cert_file_env"]=> "SSL_CERT_FILE"
["default_cert_dir"]=> "/usr/lib/ssl/certs"
["default_cert_dir_env"]=> "SSL_CERT_DIR"
["default_private_dir"]=> "/usr/lib/ssl/private"
["default_default_cert_area"]=> "/usr/lib/ssl"
["ini_cafile"]=> ""
["ini_capath"]=> ""
}

So to solve this Solutions I tried:

I created my localhost certificate Ref: https://www.digicert.com/ssl-support/openssl-quick-reference-guide.htm#:~:targetText=OpenSSL%20is%20an%20open%2Dsource,and%20how%20to%20use%20them. but not sure when to put that certificate so placed in /usr/local/share/ca-certifcates/ folder and tried curl https://google.com/ --cacert /usr/local/share/ca-certifcates/localhost.pem - still same error
Edited my /usr/local/etc/php/php.ini php configuration file to add

curl.cainfo="/usr/local/share/ca-certificates/localhost.pem"

openssl.cafile = "/usr/local/share/ca-certificates/localhost.pem" just to find the - same error

I have been trying this with no luck. I have literally scanned through almost all of stack overflow posts related to curl, OpenSSL, SSL, Docker, etc and couldn't find the answer.

FURTHER UPDATES & FINDINGS
1. Surprisingly I wonder, the 'cacert.pem' the file provided at https://curl.haxx.se/ca/cacert.pem (note - https) to solve the SSL problem, whereas I am not able to connect to secure links, how can I even get to download pem file from https? kinda deadlock? Anyways, so I tried to download using wget http://curl.haxx.se/ca/cacert.pem a non-secure way to get the pem file and I got the output as :

root@b6df004de9df:/usr/local/etc/openssl# wget http://curl.haxx.se/ca/cacert.pem

And since its a Linux server and no GUI available, so seems an only possible way for me to download is via Terminal, not a browser.

That being said, I manually created cacert.pem file and entered content in it from curl.haxx.se. And then updated php.ini with the following changes and restarted the apache server.

curl.cainfo: /usr/local/etc/openssl/cacert.pem & openssl.cafile: /usr/local/etc/openssl/cacert.pem Still - curl: (60) SSL certificate problem: unable to get local issuer certificate

Updated php.ini for curl.cainfo and openssl.cafile with "/usr/lib/ssl/cert.pem" as its "default_cert_file" according to 'openssl_get_cert_locations()'. Restarted apache server. Tried with curl https://www.google.com - Still curl: (60) SSL certificate problem: unable to get local issuer certificate
Created a new directory 'ssl' as it was not present already and assuming, By default, the OpenSSL directory is /usr/local/ssl. Created cacert.pem file in that folder. Updated curl.cainfo and openssl.cafile entries in php.ini with this new updated path. To be on a safer side, executed update-ca-certificates --fresh just in case. Restarted the apache server. Tried with curl https://www.google.com - Still curl: (60) SSL certificate problem: unable to get local issuer certificate

On side note full output of cURL command :

root@b6df004de9df:/usr/lib/ssl/certs# curl https://thawte.com
curl: (60) SSL certificate problem: unable to get local issuer certificate
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.

Finally, got the issue sorted out. Actually, I never had to set the curl.cainfo OR openssl.cafile or any other updates for that matter like downloading the certificate to use in container etc. After I create a Self Signed Certificate, I had to Configure Apache to Use SSL and Make those changes related SSL into Apache server and we're all set.
