test

This generated README.md file loosely follows a popular template._

One paragraph of project description goes here.

Getting Started

You create a file expand.txt that looks like this:

account
user
group

Then you create the app using atlas-cli, substitute below with the container registry you would use with this app.

atlas init-app -name=test -expand=expand.txt -db=true -registry=<your registry> -gateway -health -helm

There is an issue with atlas-cli. The gentool which is used to generate the code is trailing the version used by atlas-cli, result is that there is an older version of grpc-gateway code gen versus go module declarations. When you try to compile you get errors, for now we patch go.mod:

diff --git a/go.mod b/go.mod
index 46adf47..0c3ad71 100644

It should compile:

go mod vendor
go build -o test cmd/server/*.go

You should be able to run the full make:

make all

You will see a successful make and in my case an image built for my registry:

Successfully tagged soheileizadi/test:e07806a-unsupported

Lets start running it local, this assumes you have postgres database running on localhost listening to 5432, we do this by running a docker postgres image:

docker run -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=atlas_cli_test -p 5432:5432 postgres

Make sure it is running

❯ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

Put a rule in make file to run migration locally using migrate tool:

DATABASE_HOST=localhost:5432
DATABASE_NAME=atlas_cli_test
DATABASE_USER=postgres
DATABASE_PASSWORD=postgres

migrate:
    @migrate -database 'postgres://$(DATABASE_USER):$(DATABASE_PASSWORD)@$(DATABASE_HOST)/$(DATABASE_NAME)?sslmode=disable' -path ./db/migration up

You can psql to look at the tables that are created:

psql postgres://postgres:postgres@localhost:5432/atlas_cli_test

You can standup a kubernetes pod and forward the port for postgres:

kubectl port-forward --namespace test svc/postgresql 5432:5432

PGPASSWORD=postgres dropdb -h 127.0.0.1  -U postgres -p 5432 atlas_cli_test
PGPASSWORD=postgres createdb -h 127.0.0.1  -U postgres -p 5432 atlas_cli_test
make migrateup

Atlas CLI is missing a couple of migration files you can for now copy them from here: 00001_set_updated_at_func.down.sql 00001_set_updated_at_func.up.sql

Migration should work now:

❯ make migrate
migrate -database 'postgres://localhost:5432/test?sslmode=disable' -path ./db/migration up
1/u set_updated_at_func (7.167753ms)
2/u accounts (14.064373ms)
3/u users (20.039864ms)
4/u groups (25.608444ms)

You can now run the app:

❯ ./test
...
 ./test

Now we get version output but other endpoints are not working!

curl http://localhost:8080/atlas-cli-test/v1/version | jq
{
  "version": "0.0.1"
}

curl -H "Authorization: Bearer $JWT" http://localhost:8080/atlas-cli-test/v1/users -d '{"name": "user-1"}' | jq

curl -H "Authorization: Bearer $JWT" http://localhost:8080/atlas-cli-test/v1/users | jq
{
  "error": [

      "message": "Not Implemented"
    }
  ]
}

This is a problem with endpoint registeration, you need to modify main.go and replace the following commit and changes to:

• grpc.go
• main.go
• servers.go
• endpoints.go

After these changes you should be reach the accounts endpoint and others:

curl http://localhost:8080/atlas-cli-test/v1/accounts | jq
{}

Now you can add an Account:

curl http://localhost:8080/atlas-cli-test/v1/accounts -d '{"name": "acme", "description": "Acme Corp"}' | jq
{
  "result": {
    "id": "atlas-cli-test/accounts/1",
    "name": "acme",
    "description": "Acme Corp"
  }
}

curl -X PATCH http://localhost:8080/atlas-cli-test/v1/accounts/1 -d '{"description": "Acme Inc"}' | jq
{
  "result": {
    "id": "atlas-cli-test/accounts/1",
    "name": "acme",
    "description": "Acme Inc"
  }
}

curl -X PUT http://localhost:8080/atlas-cli-test/v1/accounts/1 -d '{"name": "Acme New"}' | jq
{
  "result": {
    "id": "atlas-cli-test/accounts/1",
    "name": "Acme New"
  }
}

curl http://localhost:8080/atlas-cli-test/v1/accounts | jq
{
  "results": [
    {
      "id": "atlas-cli-test/accounts/1",
      "name": "Acme New"
    }
  ]
}

curl -X DELETE http://localhost:8080/atlas-cli-test/v1/accounts/1 | jq
{}
