This feature will reduce repetitions in your scripts 😉

that's awesome!

Erik Osterman (Cloud Posse)over 7 years ago

also, like that you support a list under script

Erik Osterman (Cloud Posse)over 7 years ago

are those ultimately joined as one script or each run in their own shell?

Erik Osterman (Cloud Posse)over 7 years ago

this!!

Erik Osterman (Cloud Posse)over 7 years ago

I want.

Erik Osterman (Cloud Posse)over 7 years ago

basically we can create a variant library, then create a cli that imports various capabiltiies

Erik Osterman (Cloud Posse)over 7 years ago

for example, we can create a helm lib, and a helmfile lib and a kops lib and a terraform lib with useful tricks

Erik Osterman (Cloud Posse)over 7 years ago

e.g. for terraform, automating force-unlock

Erik Osterman (Cloud Posse)over 7 years ago

then in the final implementation, we can include the libs that we want into our cli. for example, one customer might not use kops, so we wouldn't need to import that lib.

and this https://github.com/mumoshu/variant/issues/51!

Erik Osterman (Cloud Posse)over 7 years ago

so cool

@mumoshu I am trying to run an interactive SSH session inside of variant, should that work?

       tasks:
          # Connect to bastion instance
          bastion:
            description: "Connect to the bastion"
            script: |
              set -e
              source <(chamber exec kops -- sh -c 'export -p')
              eval $(ssh-agent -s)
              ssh-add - <<<${KOPS_SSH_PRIVATE_KEY}
              ssh -A admin@bastion.${KOPS_CLUSTER_NAME}
              eval $(ssh-agent -k) >/dev/null

I love it!!!


mixins:
  chamber: &chamber
    source <(chamber exec kops -- sh -c 'export -p' 2>/dev/null)

Erik Osterman (Cloud Posse)over 7 years ago

Then anywhere I want chamber, I can just do this:


          bastion:
            description: "Connect to the bastion using ssh-agent forwarding"
            interactive: true
            script:
            - *chamber
            - |
              set -e
              eval $(ssh-agent -s)
              ssh-add - <<<${KOPS_SSH_PRIVATE_KEY}
              ssh -A admin@bastion.${KOPS_CLUSTER_NAME}
              eval $(ssh-agent -k) >/dev/null

this is shell scripting on steroids

Erik Osterman (Cloud Posse)over 7 years ago

I tried to change the default runner by adding

Erik Osterman (Cloud Posse)over 7 years ago


runner:
  command: "bash"
  args: ["-ex", "-c"]

Erik Osterman (Cloud Posse)over 7 years ago

should that work?

Erik Osterman (Cloud Posse)over 7 years ago

(in the global scope)

Erik Osterman (Cloud Posse)over 7 years ago

Ahhh yes, ultimately this becomes an issue.

Erik Osterman (Cloud Posse)over 7 years ago

I would like to discuss some idea that @Igor Rodionov had today

Erik Osterman (Cloud Posse)over 7 years ago

I am afk, so will pick up later

mumoshuover 7 years ago

btw: https://github.com/mumoshu/variant/issues/51 and https://github.com/mumoshu/variant/issues/52 has been resolved and included in variant v0.20.0 (haven’t done much testing yet. briefly verified to work with github sources though

Wrote up an another issue that fills one of big missing pieces(to me): https://github.com/mumoshu/variant/issues/57
