aponiatowski / gossh Goto Github PK

Parse bash scripts to avoid additional scripting to run with the tool

simplify using the command. eg. gossh all run my-bash-script.sh

gossh [seq/groups/all] update system (or os, haven't decided yet)

this should run a full distribution update/upgrade on all servers, os must be specified in pool.yml file in order for it to work.

check if there is a ssh key specified, if not, then use password auth

ssh: handshake failed: knownhosts: key mismatch
panic: runtime error: invalid memory address or nil pointer dereference

This will need a quick patch...

noun
"a minimum or starting point used for comparisons"

similar to what the other tools would call playbooks/cookbooks/manifests/etc. I will design and plan how to simplify it, to the point that one does not need to learn a tool intensively. It needs to be fluent, obvious and intuitive.

• Create layout/template yaml file for constructing baselines

• Create 'apply' function to apply the baseline

• Create 'check' function to check if the baseline is compliant

• Create 'verify' function to check/verify the baseline you have created (a baseline check to see if you would encounter errors before running it)

gossh [seq/groups/all] update

Should update all servers on major distributions (popular package manager, eg. yum, dnf, apt-get, pacman, zypper,etc )

gossh status

should log the status of all servers. This will run concurrently, instead of giving the option of running them in groups, or sequentially.

I will think of a design, that would be readable and useful as it progresses

This will be needed in the very near future, as one will need sudo in most automation tasks.

Password will become a requirement in the config file, when Need_Sudo is set to yes/true

I will need to resolve this issue, as currently it is set to HostKeyCallback: ssh.InsecureIgnoreHostKey()

The need will arise to use HostKeyCallback: ssh.FixedHostKey() , for security concerns.

Conditions will have to be put in place, where if it does not find a knownhosts file (windows, if not using bash/putty), it will have to use InsecureIgnoreHostKey and if it does find it, it needs to parse it and check if they match the config file.

Another condition will then have to be put in place, that if the servers in the config file, does not match the knownhosts, it should either automatically add them, or print a recommendation to use another option (thinking of adding 'add' as an option to sequentially add servers to the knownhosts file)

this will be an interesting one... as one would need to run a specific group, which sounds obvious and trivial, but when one has the ability to write out full sentences in your pool.yml, that can become... tricky.

• gossh group "the long group name" command
  which makes it easier, but not very fluent typing and annoying to add quotations in the terminal

or

• gossh group the long group name command
  which would be a tough one... parse the group names into string slices and get the length of that, and use that number to check if the name is correct? eg if the group name in the pool is [3], then it would check the cli args from [1:3+3] (numbers could be wrong... its late, I'm tired)

if one runs gossh groups command , and you have 2 servers in the first group, and 1 in the second group... it would run through the first group just fine (with its errors and log them). but the second group runs twice, with 1 success, even though the second one failed (intentionally tested this)

It is most likely a logic error, which I can't see yet. Or alternatively, find another progress bar to replace the current one. There are a few dynamic ones out there...

I would like to either change the progress bar, or make changes to the progress bar, to show some color. For eg. as the bar progresses, it should show an indication of failed/success, via green or red colors in the progress bar. Also some of the output can also be spruced up a bit.

• Colorize progress bar

• Colorize some of the output

gossh [seq/groups/all] install package
gossh [seq/groups/all] uninstall package

Should install/uninstall packages on all servers.

• Install

• Uninstall
