Define code names corresponding to your server environment:

• testing (test servers)
• staging (staging servers)
• production (production servers)

Populate apt.mycompany.com

# apt-get install \
   --download-only \
   escenic-content-engine-6.3 \
   escenic-sse-proxy-1.0
# reprepro \
    --keepunreferencedfiles \
    -Vb /var/www/html/apt.mycompany.com \
    --component non-free \
    includedeb \
    development \
    /var/cache/apt/archives/escenic-content-engine-6.3_6.3.0-11_all.deb

Use apt.mycompany.com 📦

On pres1.staging.mycompany.com, put in its /etc/apt/sources.list.d/escenic.list

deb https://user:pass@apt.mycompany.com staging main non-free

Can now install packages from it:

# apt-get update
# apt-get install escenic-content-engine-6.3 cue-web-2.3

Promote a package from staging to production

MyCompany QA has verified version 6.3.0-11 on staging and want to roll this out in production:

# reprepro \

    -Vb /var/www/html/apt.mycompany.com \
    --component non-free \
    includedeb \
    production \
    /var/cache/apt/archives/escenic-content-engine-6.3_6.3.0-11_all.deb

Use apt.mycompany.com 📦🔒

Optionally, specify code name when installing packages:

# apt-get install -t staging escenic-content-engine-6.3

Use apt.mycompany.com 📦🔒

Optionally, pin package(s):

No matter what's available, this machine should use version 1.2.3 of "foo-server"
