It occurs that `config/deploy.rb` has `lock &#39;3.1.0&#39;`.  

It was enough to change it to `&#39;3.2.0&#39;` and now it&#39;s working.

Shouldn&#39;t Bundler handle this for you? If you have the version specified in your Gemfile, you can remove the lock version in config/deploy.rb. Then a `bundle exec cap production deploy` should do the trick.

CentOS. Need to find files modified in last 30 days to see if any of them have been infected with malware.

I tried this:

    root@server [/home/someuser/public_html/]# find . -mtime +30
     -exec ls -l {} &gt; last30days.txt \;

But instead of the last 30 days, it seems to have found everything. 22,000 files.

I have a contact form and after submitting I am getting a Net::SMTPAuthenticationError `535-5.7.8 Username and Password not accepted`

I&#39;ve this worker that runs for ever.

    class Worker
      include Sidekiq::Worker
      sidekiq_options queue: &quot;infinity&quot;, retry: true

      def perform(params)
        # ...
        self.class.perform_in(30.seconds, params)
      end
    end

The problem is that I load workers on start up, like this. `config/initializers/load_workers.rb`

    Rails.application.config.after_initialize do  
      if ENV[&quot;SIDEKIQ&quot;] == &quot;1&quot;
        Worker.perform_async({})
      end
    end

Using this to start sidekiq `SIDEKIQ=1 sidekiq --verbose --environment production -C config/sidekiq.yml`.

This means that old workers as to stop, both those currently running but also the ones being rescheduled.

I tried running this on start up (just before loading new works), but that didn&#39;t work.

    q = []
    q += Sidekiq::RetrySet.new.select { |job| job.klass.match(/Worker/) }
    q += Sidekiq::Queue.new(&quot;infinity&quot;).select { |job| job.klass.match(/Worker/) }
    q += Sidekiq::ScheduledSet.new.select { |job| job.klass.match(/Worker/) }
    q.each(&amp;:delete)

After 5-ish deploys there are bunch of duplicate workers in the queue scheduled for later. So, is there a way to clear everyting in one queue and prevent already running jobs from rescheduling?

I&#39;m using sidekiq 3.0.

I created a Rails application, using Rails 4.1, from scratch and I am facing a strange problem that I am not able to solve.

Every time I try to deploy my application on Heroku I get an error 500:

    Missing `secret_key_base` for &#39;production&#39; environment, set this value in `config/secrets.yml`

The `secret.yml` file contains the following configuration: 

    secret_key_base: &lt;%= ENV[&quot;SECRET_KEY_BASE&quot;] %&gt;

On Heroku I configured the &quot;`SECRET_KEY_BASE`&quot; environment variable with the result of the `rake secret` command. If I launch `heroku config`, I can see the variable with the correct name and value.

Why am I still getting this error?

When I attempt to run &quot;rake test&quot; on a local postgres database, it throws the above exception.

Here is my pg_hba.conf file:

    password:

In the real database.yml, &#39;username&#39; is replaced with my actual user name that I am logged in as.  Since the authentication method is defined as &#39;peer&#39;, no password should be required.

I have also taken care to restart Postgres 

    sudo -u postgres pg_ctlcluster 9.3 main restart

What else am I missing here?

My understanding of a canary release is that it&#39;s a partial release to a subset of production nodes with sticky sessions turned on. That way you can control and minimize the number of users/customers that get impacted if you end up releasing a bad bug.

My understanding of a blue/green release is that you have 2 mirrored production environments (&quot;blue&quot; and &quot;green&quot;), and you push changes out to all the nodes of either blue or green at once, and then use networking magic to control which environment users are routed to via DNS.

So, before I begin, if anything I have said so far is incorrect, please begin by correcting me!

Assuming I&#39;m more or less on track, then a couple of questions about the two strategies:

 * Are there scenarios where canary is preferred over blue/green, and vice versa?
 * Are there scenarios where a deployment model can implement both strategies at the same time?

Canary release strategy vs. Blue/Green

I have created a &#39;helloworld&#39; iOS app with `cordova` using there [documentation](http://cordova.apache.org/docs/en/3.0.0/guide_cli_index.md.html). The app successfully runs when I run `cordova emulate ios`. What I can&#39;t do, is while deploying when I run `cordova build --release`. It doesn&#39;t create any `.ipa` files there. All I find is a `Helloworld.build` file in the `PROJECT_ROOT/platforms/ios/build` directory. Am I missing something here?

How can I deploy (create .ipa) iphone app using &#39;cordova build ios --release&#39;?

I have a few Docker containers running like:

 - Nginx
 - Web app 1
 - Web app 2
 - PostgreSQL

Since Nginx needs to connect to the web application servers inside web app 1 and 2, and the web apps need to talk to PostgreSQL, I have linkages like this:

 - Nginx --- link ---&gt; Web app 1
 - Nginx --- link ---&gt; Web app 2
 - Web app 1 --- link ---&gt; PostgreSQL
 - Web app 2 --- link ---&gt; PostgreSQL

This works pretty well at first. However, when I develop a new version of web app 1 and web app 2, I need to replace them. What I do is remove the web app containers, set up new containers and start them.

For the web app containers, their IP addresses at first would be something like:

 - 172.17.0.2
 - 172.17.0.3

And after I replace them, they will have new IP addresses:

 - 172.17.0.5
 - 172.17.0.6

Now, those exposed environment variables in the Nginx container are still pointing to the old IP addresses. Here comes the problem. How do I replace a container without breaking linkage between containers? The same issue will also happen to PostgreSQL. If I want to upgrade the PostgreSQL image version, I certainly need to remove it and run the new one, but then I need to rebuild the whole container graph, so this is not ideal for real-life server operation.

How do I set up linkage between Docker containers so that restarting won&#39;t break it?

I am trying to stage a project from a working directory to a server (same machine). Using the following code:

    gulp.src([
        &#39;index.php&#39;,
        &#39;css/**&#39;,
        &#39;js/**&#39;,
        &#39;src/**&#39;,
    ])
    .pipe(gulp.dest(&#39;/var/www/&#39;));

I would expect to see all the files copied. However it flattens the dir structure - all directories are copied but every file is placed in the root `/var/www`

Gulp seems like a great build tool but copying items should be a simple process surely?


How do I copy directories recursively with gulp?

I&#39;m developing an enterprise application. When I was testing it in iOS8 beta I saw the following alert view:

    Untrusted App Developer
    Do you trust the developer &quot;iPhone Distribution: ---&quot; to run apps on you iPad?

It only appears the first time.
Can I avoid it somehow? And what is it related to?

I&#39;ve switched to using [environment variables for configuration](http://12factor.net/config) and it works very well - except when I have to deploy or run tasks with capistrano.

Capistrano 3 seems to execute each command prefixed with `/usr/bin/env` which erases any environment variables I&#39;ve set through `.bashrc`.

*EDIT* - on doing some more reasearch, this might not be the issue, the issue might be because capistrano executes as a non-login, non-interactive shell and does not load `.bashrc` or `.bash_profile`. Still stuck, though.

What would be the best way of making sure the environment vars are set when capistrano executes its tasks?
