Need help fixing salt stack code to copy file from s3 bucket - salt-stack

I wrote this code to pull file from S3 bucket, change the file permission and execute the code. However, it's not working for me.
download_file_from_s3:
file.managed:
- name: /opt/agent_installer.sh
- source: s3://bucket_name/install.sh
change_file_permission:
file.managed:
- source: /opt/install.sh
- user: root
- group: root
- mode: 0744
run_rapid7_script:
cmd.run:
- name: /opt/install.sh

There are a couple of changes I can suggest looking at your code.
You are saving the file from S3 as /opt/agent_installer.sh with file.managed, let's consider that there is no issue with this.
Now, the first thing that we obviously need to change in subsequent tasks, is to use this. Not /opt/install.sh. Also file.managed can be used once to download the file, change ownership, and permissions. So your SLS can look like:
download_file_from_s3:
file.managed:
- name: /opt/agent_installer.sh
- source: s3://bucket_name/install.sh
- user: root
- group: root
- mode: 0744
run_rapid7_script:
cmd.run:
- name: /opt/agent_installer.sh
There is also a cmd.script state which can be used directly with the S3 URL as source, so there is no need to have file.managed at all.
So, just 1 state like below should be sufficient:
run_rapid7_script:
cmd.script:
- source: s3://bucket_name/install.sh
If you do have issue with downloading file from S3, then see the documentation on how to configure it correctly.

SaltStack - Use salt:// to define working directory in cmd.run state

I'm quite new to SaltStack and I'm wondering if there's a way to use salt:// URI where it's not supported natively.
In this case I would execute a command in a specific directory and I would like to specify the directory using salt:// like the following:
test_cmd:
cmd.run:
- name: echo a > test
- cwd: salt://my-state/files/
which actually doesn't work giving the error
Desired working directory "salt://my-state/files/" is not available
Is there a way to do it?
I don't think there's a way to do it the way you want, but you might be able to get what you need by combining file.recurse with cmd.run or cmd.wait:
test_cmd:
file.recurse:
- name: /tmp/testcmd
- source: salt://mystate/files
cmd.wait:
- name: echo a > test
- cwd: /tmp/testcmd
- watch:
- file: test_cmd
That copies the salt folder to the minion, then uses the copy as the working directory.

How to transfer file only when it changed in salt?

I am using the following way to provide bundled software project to salt minions:
proj-archive:
cmd:
- run
- name: "/bin/tar -zxf /home/myhome/Proj.tgz -C {{ proj_dir }}"
- require:
- file: /home/myhome/Proj.tgz
- {{ proj_dir }}
file:
- managed
- user: someone
- group: someone
- mode: '0600'
- makedirs: True
- name: /home/myhome/Proj.tgz
- source: salt://Proj.tgz
As far as I can tell, it does the job, but these rules are always active, even when archive have not changed. This brings unnecessary delays in deployment. In a similar situation, for example, service restart with watch clause on a file, it is possible to restart when file changed. How to tell salt to copy file over network only when it changed? Is there any automatic way to do it?
The Proj.tgz in salt directory is a symlink to file location, if it matters.
The archive.extracted is not that useful, because it does not trigger when changes are inside files, no files added or removed in the archive.
Some relevant info https://github.com/saltstack/salt/issues/40484 , but I am unsure of resolution / workaround.
You can replace both states with salt.states.archive. It might look like this:
proj-archive:
archive.extracted:
- name: {{ proj_dir }}
- source: salt://Proj.tgz
- user: someone
- group: someone
- source_hash_update: True
The key feature here is source_hash_update. From the docs:
Set this to True if archive should be extracted if source_hash has changed. This would extract regardless of the if_missing parameter.
I'm not sure whether or not the archive gets transferred on each state.apply. But I guess it will not.

salt stack source bashrc each time bashrc is updated

The bashrc files for my minions is a managed file, now I need to source the bashrc file each time it is changed is there a way to do that in salt.
Currently I have this
/home/path/bashrc:
file.managed:
- name: /home/path/.bashrc
- source: salt://dir/bashrc
- user: path
- group: path
cmd.run:
- name: source /home/path/.bashrc
- user: path
is this the correct way to do this ?
You can't and don't need to do that - source only works for the currently open terminal session. Salt can't (or shouldn't) abort/interrupt existing terminal sessions just to source a new bashrc.
A new version of bashrc will be sourced automatically when the user logs in next time.

Remove all files not managed by my script

I have a formula that reads in the pillar a list of items to create some config files, like this:
fileA
config:
- some other config
- ...
fileB
config:
- other configs
the problem is, in the parent folder there is a lot of temporary files and other created by the system.
How can I remove all the files not managed by my script? Fot the time being I am doing like this
directory_clean:
file.directory:
- name: {{ directory }}
- clean: True
But this way all my files are being removed and added again. Is there a better solution?
Depending on how your salt tree is set up, you should be able to do this with file.recurse:
manage_directory:
file.recurse:
- name: /etc/something
- source: salt://something/files
- clean: True
- template: jinja # if needed
This assumes there is a directory in your salt tree containing all and only the files you want.

Problems with basic usage of saltstack apache-formula

I'm new to Saltstack and I'm just trying to do some simple installs on a subset of minions. I want to include Environments so I have my file roots as:
file_roots:
base:
- /srv/salt/base
dev:
- /srv/salt/dev
qa:
- /srv/salt/qa
stage:
- /srv/salt/stage
prod:
- /srv/salt/prod
I set up the git backend:
fileserver_backend:
- git
- roots
I'm using gitfs set as:
gitfs_remotes:
- https://github.com/saltstack-formulas/postgres-formula
- https://github.com/saltstack-formulas/apache-formula
- https://github.com/saltstack-formulas/memcached-formula
- https://github.com/saltstack-formulas/redis-formula
So I have the master set up and I add top.sls to /srv/salt/stage with
include:
- apache
stage:
'stage01*':
- apache
But I get an error when I execute
salt -l debug \* state.highstate test=True
Error
stage01.example.net:
Data failed to compile:
----------
No matching sls found for 'apache' in env 'stage'
I've tried many ways and the master just can't seem to find the apache formula I configured for it.
I found the answer and it was sitting in the Saltstack docs the whole time.
First you will need to fork the current repository such as postgres-formula.
Depending on the environment create a branch of the same name in your newly create fork of the repo.
So for example I wanted to use postgres in my stage environment. So it wouldn't work until I created a branch named stage ined my forked repo of postgres-formula then it worked like a charm.
