    Hi, I would like to use Capistrano to automate deployment commands that I run manually. However this isn&quot;t a Rails app. Not sure how important that is.I have 3 scenarios. One deploys everything, one deploys &quot;System B&quot; updates, one deploys &quot;System A&quot; updatesI&quot;d like a Capistrano expert to architect the best approach.- Can this be done with Capistrano 2? 3 looks great but my current project doesn&quot;t use git. And switching everything over is a pain.- Assuming yes, help create the Cap scripts to deployHere are the scenarios:===Deployment scenario 1: Both System A and System B===2) Confirm file(s) are formatted correctlycd $HOMEsvn updateperl t/Receiver_Conf.t# must exit correctly, no errors3) Create new domainscd $HOMEsvn updateperl bin/ --first4) On server8, server1cd $HOMEsvn updateperl bin/ confirm all is ok5) On server4, server5, server7, serverS, serverFcd $HOMEsvn updateperl bin/ confirm all is ok6) Sanity checks: serverF: 0 processes server1: 1 process server4: 0 processes server5: 2 processes server7: 3+ processes + bin/ server8: 1 process + bin/ serverS: 3 processes===Deployment scenario 2: System B only===2) Confirm file(s) are formatted correctlycd $HOMEsvn updateperl t/Receiver_Conf.t# must exit correctly, no errors3) Create new domainscd $HOMEsvn updateperl bin/ --first4) On server7, server4, server1, serverFcd $HOMEsvn updateperl bin/ confirm all is ok6) Sanity checks: server1: 1 process server4: 0 processes server7: 3+ processes + bin/ scenario 3: System A only===2) Confirm file(s) are formatted correctlycd $HOMEsvn updateperl t/Receiver_Conf.t# must exit correctly, no errors3) Create new domainscd $HOMEsvn updateperl bin/ --first4) On server8, serverS, server5, serverFcd $HOMEsvn updateperl bin/ confirm all is ok6) Sanity checks: server5: 2 processes server8: 1 process + bin/ serverS: 3 processesThis could be restructured somewhat to make it more capistrano-friendly.

    The full design / UI is complete.The site will use the gem, and overall has a minimal feature set.1. Users can create a new page ( - name availability check - create password2. To add new content to a page, a user must enter the page password.3. Submit URL to add content to page ( gem pulls content & embeds it)You’ll also need to know some Jquery / front-end to get all the content to display correctly, light boxes, fonts, etc.Ideally we’d use digital ocean or heroku for hosting, and possibly AWS if it’s needed.

    I&quot;ve started building the site using a wrap-bootstrap theme, completely stopped and am picking it up again. I honestly don&quot;t know if it will be easier for me to just build it, or to work someone to get things completed. I&quot;m sending over a description of what I&quot;m looking to get done. I can link to the repository on Github.Hi level overview - I&quot;m doing a podcast where I talk to entrepreneurs in NYC about their companies. The podcast is hosted on podbean (, but their site sucks and so I was planning to build my own site. I think it&quot;s a fairly simple setup. I would like-Home PageIndex page for all episodes - This template calls it a GalleryEpisode Page - each episode has it&quot;s own pageAbout Page - will be static. Admin pages - to create, edit and delete episodes.I don&quot;t want a player on my site - I&quot;m fine if my site just links to the Podbean site with a player.I&quot;ve created an episode Model the will populate details of the show and index pages. Devise would be my choice for the user/admin concept. Once it&quot;s completed I&quot;ll host this on Heroku - if that makes a difference for the DB/setup. Finally, I&quot;ll want to add a picture to each episode.The basic site is there, and the model is created. I need the model details to populate the views correctly (including pictures) and an admin concept created so that I can create and edit. I&quot;d imagine this would be a few (2-3) hours of work for a good developer at most. For a new developer (like me) it might take about 10 hours. I&quot;m interested to see bids. Can send the link to the repo as needed.Best,Mike
