py-volumn-test 0.0.2

A small package targeting to help on python project packaging process

py_volumn_test

This simple volumn testing framework for linux platform.

Requirements

The application requires

1. python 3.12+
2. requires df command
3. hashicorp vault

Setup

Hashicorp Vault

Assume

1. we create secret on mount point (mp)
2. we create secret on path (abc)
3. we create a policy of policy-mp-abc
4. we create a approle of ar-mp-abc

Create policy

by creating a hashicorp policy xxx.hcl

# assume `{mount_point}` is `mp`
# assume `{path}` is `abc`
# access the secret in cli `vault kv get mp/abc`
# The actual path of the secret is `mp/data/abc`
path "{mount_point}/data/{path}/*" {
        capabilities = ["read"]
}

Insert or update the policy by

vault policy write {policy_name} {policy_file}
# vault policy write policy-mp-abc xxx.hcl

Create app role

# ------ create app role
vault write auth/approle/role/{app role name} token_policies="{policy name}" token_ttl="15m" token_max_ttl="2h"
# vault write auth/approle/role/ar-mp-abc token_policies="policy-mp-abc" token_ttl="15m" token_max_ttl="2h"
vault write auth/approle/role/{app role name} token_policies="{policy name}" token_ttl="15m" token_max_ttl="2h"

# ------ get role id
# The command return the role id
vault read auth/approle/role/{app role name}/role-id
# vault read auth/approle/role/ar-mp-abc/role-id

# ------ get secret id
# The command return the secret id (the secret is force to be generated, without re-view the secret id)
vault write -f auth/approle/role/{app role name}/secret-id
# vault write -f auth/approle/role/ar-mp-abc/secret-id

# ------ login the vault in env
# assume the role_id is `vault_role_id`
# assume the secret_id is `vault_secret_id`
export VAULT_TOKEN="$(vault write -format=json auth/approle/login role_id=$vault_role_id secret_id=$vault_secret_id | jq -r '.auth.client_token')"

Create secret

vault kv put mp/abc \
    api_key=$api_key \                     # api key is the api key for restdb.io
    host=$host \                           # host is url
    collection_name=$collection_name \     # collection name is the collection name
    filter_name=$filter_name \             # filter name is the configuration name to filter
    bootstrap_id=$bootstrap_id             # the entry point to access

Run application

df | \
    docker run \
        -e VAULT_ADDR="$VAULT_ADDR" \
        -e vault_role_id="$vault_role_id" \
        -e vault_secret_id=$vault_secret_id \
        -e vault_mount_point=$vault_mount_point \
        -e vault_secret_path=$vault_secret_path \
        -i py-volumn-test
