Put this at the top of your scheduled bash script:

curl -s https://s3.amazonaws.com/assets.heroku.com/heroku-client/heroku-client.tgz | tar xz
mv heroku-client/* .
rmdir heroku-client

then, for example, you can call:

<pre><code>heroku pg:reset HEROKU_POSTGRESQL_YELLOW_URL --app myapp-staging --confirm myapp-staging
heroku pgbackups:restore HEROKU_POSTGRESQL_YELLOW_URL `heroku pgbackups:url --app myapp-production` --app myapp-staging --confirm myapp-staging
</code></pre>

and poof! Staging database is updated from production database.

blocks|key|3028337|text|正如Heather+Piwowar所说，你确实可以自己下载并解压heroku收费带，但之后就不需要移动文件了。下面是一个简短的版本：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3028338|curl+-s+https://s3.amazonaws.com/assets.heroku.com/heroku-client/heroku-client.tgz+%7C+tar+xz

As Heather Piwowar said, you can indeed download and untar the heroku tollbelt yourself, but no need to move files around after this. Here is a shorter version:

<pre><code>curl -s https://s3.amazonaws.com/assets.heroku.com/heroku-client/heroku-client.tgz | tar xz
PATH="/app/heroku-client/bin:$PATH"
</code></pre>

You can now use the <code>heroku</code> command as you wish.

For authentification, you may want to set the <code>HEROKU_API_KEY</code> env var (using <code>heroku config:set HEROKU_API_KEY=1234567890 -a your-app-name</code>).

Also, note that the first use of the <code>heroku</code> command will run longer than expected because it will try to install the latest version, dependencies and core plugins.

blocks|key|3028378|text|您可以使用Heroku+Scheduler并配置以下命令(例如)来创建数据库备份：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3028379|curl+-s+https://s3.amazonaws.com/assets.heroku.com/heroku-client/heroku-client.tgz+\
+%7C+tar+xz+&&+./heroku-client/bin/heroku+pg:backups:capture+-a+you-app-name-here|code-block|syntax|javascript|3028380|为此，您需要添加一个名为HEROKU_API_KEY的配置变量，并从您的帐户页面将其值设置为"API+Key“值。|style|CODE|3028381|entityMap|0|LINK|mutability|MUTABLE|url|https://elements.heroku.com/addons/scheduler^0|5|G|0|0|0|C|E|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|F|7|Y|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|Z|8|@$A|10|B|11|K|L]]|9|@]|C|$]]|$1|M|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|N|$O|$5|P|Q|R|C|$S|T]]]]

You can use <a href="https://elements.heroku.com/addons/scheduler" rel="nofollow noreferrer">Heroku Scheduler</a> and configure the following command (as an example) to create a database backup:

<pre><code>curl -s https://s3.amazonaws.com/assets.heroku.com/heroku-client/heroku-client.tgz \
 | tar xz &amp;&amp; ./heroku-client/bin/heroku pg:backups:capture -a you-app-name-here
</code></pre>

For this to work, you need to add a Config Variable named <code>HEROKU_API_KEY</code> and set its value to the "API Key" value from your Accounts page.

blocks|key|3028405|text|因为Heroku在构建包完成运行后锁定了文件系统，所以其他解决方案对我都不起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3028406|有一个第三方构建包可以为您安装CLI。首先，将身份验证密钥设置为应用程序上的ENV变量：|3028407|heroku+config:set+HEROKU_API_KEY=`heroku+auth:token`+-a+myapp|code-block|syntax|javascript|3028408|然后添加构建包：|3028409|heroku+buildpacks:add+https://github.com/heroku/heroku-buildpack-cli+-a+myapp|offset|length|style|CODE|3028410|重新部署您的应用程序，它应该能够通过CLI访问您的应用程序。如果你启用了https://devcenter.heroku.com/articles/dyno-metadata，你甚至可以通过$HEROKU_APP_NAME访问当前应用的名称。|3028411|entityMap|0|LINK|mutability|MUTABLE|url|https://devcenter.heroku.com/articles/dyno-metadata^0|0|0|0|0|0|25|0|10|1F|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|11|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|12|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|13|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|14|8|@$M|15|N|16|O|P]]|9|@]|A|$]]|$1|Q|3|R|5|6|7|17|8|@]|9|@$M|18|N|19|1|1A]]|A|$]]|$1|S|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|T|$U|$5|V|W|X|A|$Y|Z]]]]

None of the other solutions worked for me since Heroku locks the filesystem after the buildpacks finish running. 

There's a third-party buildpack that installs the CLI for you. First you set your auth key as an ENV variable on your app:

<pre><code>heroku config:set HEROKU_API_KEY=`heroku auth:token` -a myapp
</code></pre>

Then add the buildpack:

<code>heroku buildpacks:add https://github.com/heroku/heroku-buildpack-cli -a myapp</code>

Redeploy your app and it should be able to access your apps via the CLI. If you have <a href="https://devcenter.heroku.com/articles/dyno-metadata" rel="noreferrer">https://devcenter.heroku.com/articles/dyno-metadata</a> enabled, you can even access your current app's name with $HEROKU_APP_NAME.

I want to call heroku postgres backup/restore commands within a scheduled heroku task, but the heroku toolbelt isn't available from bash prompt, so I can't call heroku commands:

<pre><code>$ heroku run bash --app myapp
Running `bash` attached to terminal... up, run.4805
~ $ heroku --version
bash: heroku: command not found
</code></pre>

How can I get heroku commands available in my scheduled bash script?
I don't know anything about Ruby or Ruby Gems.

Access to heroku toolbelt commands in a scheduled heroku dyno?
