Combining two existing Terraform states as modules

Right now I have a Terraform project consisting of multiple directories:



root

|- stack

|- applications

   |- app1

   |- app2

   |- app3




  • Stack contains all of the common dependencies for the apps.


  • app1, app2, and app3 use remote state to refer to stack resources.

  • I currently have to run terraform apply in each of the four directories separately with separate .tfvars. (This was originally by design.)


I would like to refactor this project with a single .tf file in the root directory and the stack/app* directories as modules. I know how to do that just fine from a TF standpoint, but since this project is already deployed in two different environments, I'm trying to figure out the best way to migrate my existing stack/app* resources into a new combined state file or at least automate all the terraform import commands I'm going to need to run.



Any ideas?

  • I wonder if hand-hacking the various state files is the best approach here.

Create new schema in PostgreSQL using DBeaver

Image
0 At the beginning of my current job I had limited access to DB but recently my role is changed to superuser, admin, and owner. My colleague who was the previous DB admin is able to create a schema or change the permissions as there is a permission tab in the properties and he can change permissions by clicking easily. Would you please let me know how I can create schema and change permissions as well? Why his dbeaver looks different from me? He can easily right click on the schema folder on top of all schemas on the left side column and select create new schema while I do not have that, like the following picture I found on the internet. postgresql database-schema dbeaver share | improve this question

Deepest pit of an array with Javascript: test on Codility

Image
0 $begingroup$ This is the question from a Codility test, as a task in an interview: DeepestPit - problem description A non-empty zero-indexed array A consisting of N integers is given. A pit in this array is any triplet of integers (P, Q, R) such that: ·         0 ≤ P < Q < R < N; ·         sequence [A[P], A[P+1], ..., A[Q]] is strictly decreasing, i.e. A[P] > A[P+1] > ... > A[Q]; ·         sequence A[Q], A[Q+1], ..., A[R] is strictly increasing, i.e. A[Q] < A[Q+1] < ... < A[R]. The depth of a pit (P, Q, R) is the number min {A[P] − A[Q], A[R] − A[Q]}. For example, consider array A consisting of 10 elements such that: A[0] = 0 A[1] = 1 A[2] = 3 A[3] = -2 A[4] = 0 A[5] = 1 A[6] = 0 A[7] = -3 A[8] = 2 A[9] = 3 Triplet (2, 3, 4) is
