Continuos Deployment
David Cramer’s talk at PyCON 2012 was really good and the continuos deployment (CD) process at Disqus looks awesome.
For the Disqus’s team CD is shipping new code as soon as it is ready. It does not mean to deploy all the time but as much as you want.
It goes something like this:
- Commit
- Integrate
If it fails come back to fix it and commit it again. - Deploy
- Report

Create a Certificate Authority and Certificates with OpenSSL
Note: This is a recipe to help me next time I need to create a CA
- Install OpenSSL: sudo apt-get install openssl
- Create folders certs, conf and private wherever you are gonna have your CA
- Create a database to keep track of the certificates that you issue [echo '01' >serial ; touch index.txt]
- Create the configuration file in conf/caconfig.cnf
# # OpenSSL configuration file. # # Establish working directory. dir = /the_directory_where_you_save_the_ca_files = . [ ca ] default_ca = CA_default [ CA_default ] serial = $dir/serial database = $dir/certindex.txt new_certs_dir = $dir/certs certificate = $dir/cacert.pem private_key = $dir/private/cakey.pem default_days = 365 default_md = md5 preserve = no email_in_dn = no nameopt = default_ca certopt = default_ca policy = policy_match [ policy_match ] countryName = match stateOrProvinceName = match organizationName = match organizationalUnitName = optional commonName = supplied emailAddress = optional [ req ] default_bits = 1024 # Size of keys default_keyfile = key.pem # name of generated keys default_md = md5 # message digest algorithm string_mask = nombstr # permitted characters distinguished_name = req_distinguished_name req_extensions = v3_req [ req_distinguished_name ] # Variable name Prompt string #------------------------- ---------------------------------- 0.organizationName = Organization Name (company) organizationalUnitName = Organizational Unit Name (department, division) emailAddress = Email Address emailAddress_max = 40 localityName = Locality Name (city, district) stateOrProvinceName = State or Province Name (full name) countryName = Country Name (2 letter code) countryName_min = 2 countryName_max = 2 commonName = Common Name (hostname, IP, or your name) commonName_max = 64 # Default values for the above, for consistency and less typing. # Variable name Value #------------------------ ------------------------------ 0.organizationName_default = My Company localityName_default = My Town stateOrProvinceName_default = State or Providence countryName_default = US [ v3_ca ] basicConstraints = CA:TRUE subjectKeyIdentifier = hash authorityKeyIdentifier = keyid:always,issuer:always [ v3_req ] basicConstraints = CA:FALSE subjectKeyIdentifier = hash
- Generate CA Key and Certificate [openssl req -new -x509 -extensions v3_ca -keyout private/cakey.pem -out cacert.pem -days 365 -config conf/caconfig.cnf]
