improve output of state.apply to a lot of minions
- salt --state-output=mixed --summary "*" state.apply backups.deploy
- sudo salt-call --state-verbose=false state.apply

salt edit /etc/fstab

Edit lines in fstab e.g. Match cloudimg-rootfs and set the last 0 to a 1
- $ sudo salt "*" cmd.run "sed -i '/cloudimg-rootfs\s/ s/0$/1/ ; /cloudimg-bootfs\s/ s/0$/2/' /etc/fstab ; cat /etc/fstab"

Cloud deploy salt-cloud

With python debug pudb
- sudo pudb /usr/bin/salt-cloud --log-level info --map=/etc/salt/cloud.maps.d/softlayer-maps-SVRCONFIG-SALTMASTER.conf

Do grains lookups for mine values

Salt mine is a db of all the minion grains.

It can be used to lookup a value for another minion, e.g. IP

$ sudo salt-call mine.get 'role:mysql' network.ip_addrs grain

Using a grain to find the ip of a host with a specific role.(Using mine.sls function that is network.ip_addrs + cidr

{% set db_ip = salt.saltutil.runner('mine.get', 
                tgt='G@environment:'+grains['environment']+' and G@role:database',
                fun='internal_ip_addrs',
                tgt_type='compound')[0] %}

SaltStack errors and notes

ERROR:201905 - state.apply "Rendering SLS 'base:<xx>' failed: mapping values are not allowed in this context"

Cause was a -require: with a string ending in a colon ":"
Fix: remove the ":"

ERROR:201904 - state.apply "- Rendering SLS 'base:<xx>' failed: did not find expected alphabetic or numeric character"

Cause was un-quoted context, that received a value "*-serv.jar"
Fix
```
  context:
    file: "{{ file-src }}"
```

ERROR:201811 - mine.get - Unable to manage file: Jinja error: too many values to unpack

snippet of salt.sls state giving the error

{#% for server, addrs in salt['mine.get'](
      'G@environment:'+grains['environment']+' and G@role:webserver'
    , 'network.ip_addrs'
    , tgt_type='compound')  %}

Fix: add dictsort ???

{#% for server, addrs in salt['mine.get'](
      'G@environment:'+grains['environment']+' and G@role:webserver'
    , 'network.ip_addrs'
    , tgt_type='compound') | dictsort() }

Explanation: in for loop, python just return the dict keys same as .keys(), but if we add " | dictsort() " we get loop over dicts, not keys.
