Tin Toy

Tin Toy - A tiny Hive testnet based on tinman

Quickstart

docker run -d -p 8090:8090 inertia/tintoy:latest

Using -p 8090:8090 will expose json-rpc.

... or ...

docker run -d -P inertia/tintoy:latest

Using -P will expose all of the ports, ephemerally (see below).

As Seen from Kitematic

From the Gist

If you want to modify the scripts before deploying:

git clone https://gist.github.com/b88e7bfff8862858e54c59392e2bce20.git tintoy
cd tintoy
docker build -t myname/tintoy:mybranch .
docker run -d -P myname/tintoy:mybranch

For example, you can modify the first line of Dockerfile to switch versions of hived.

Tin Toy uses:

FROM hiveio/hive:latest

But you can switch to any branch and try it out. Suggested branches to try can be found in hive/activity.

Say we want to take a look at a branch like v0.23.0-mira. Change the first line of the Dockerfile to:

FROM hiveio/hive:v0.23.0-mira

Then build and run. At the time of writing, tag v0.23.0 was the only other tagged docker image available.

Shell In

• Use docker ps to get the name of the existing container.
• Use the command docker exec -it <container name> /bin/bash to get a bash shell in the container.

How to Use

Once the docker container has fully deployed, you'll have access to various port. Internally, the docker container responds to:

Port	Purpose
2001	p2p
8080	condenser
8090	nginx json-rpc
8091	jussi json-rpc
8092	hived json-rpc
8093	hivemind json-rpc
5000	tinman server (if enabled)

If you launched with -P (ephemeral ports enabled), you can get a list of ports:

docker ps

Which might return something like:

CONTAINER ID        IMAGE                   COMMAND                  CREATED             STATUS              PORTS                                                                                                NAMES
290810dba18e        inertia/tintoy:latest   "/bin/sh -c /app/boo…"   5 minutes ago       Up 5 minutes        0.0.0.0:32832->2001/tcp, 0.0.0.0:32831->8080/tcp, 0.0.0.0:32830->8090/tcp, 0.0.0.0:32829->8091/tcp   tintoy

Embedded Condenser

From the port list we can determine the external port for condenser. For port 8080, this example uses port 32831. Therefore, the URL to access condenser is:

http://localhost:32831

Remember, this changes whenever you execute with -P.

Default Secret Key

Normally, the secret key for a testnet is kept secret. But for a local testnet, there's no reason to keep it a secret. For tintoy, the default secret key is set in the Dockerfile:

ENV SHARED_SECRET tintoy

Which means, if you want to derive the private keys for tnman, you could use the following command:

get_dev_key tintoy owner-tnman active-tnman posting-tnman memo-tnman | jq

[
  {
    "private_key": "5K5kjWq8pY23YptZaiEkiiaKi1wafufj63nzAtaDu1epVXw9fvz",
    "public_key": "TST7uubH7SpknapasQTzW1rFho3LUn1pFmdR7X4f1cHmK22aTJYm3",
    "account_name": "owner-tnman"
  },
  {
    "private_key": "5K3NwkFwCnsSfJNACw1qm3zzojWBtP8k4rTb2kbLQ4DDR6TgGnw",
    "public_key": "TST4w9GXogQtqPprzPhp7WKZPPKWXv4KvqqMMgd5agJQCDtYLBJwA",
    "account_name": "active-tnman"
  },
  {
    "private_key": "5Jrdrbt5xfjVeHfHd5JMiJy1FfrGtuieRvzr9WFYhcdHpjgfwPY",
    "public_key": "TST883nSqJL5KbVgfdV44snPPDTStQQxfR7vj8XttsZo25sXvHAnQ",
    "account_name": "posting-tnman"
  },
  {
    "private_key": "5KB3ddeh5o3WghSM3qQaUthxVt7QZWfNYCoiAW3XYfeDki1oH9z",
    "public_key": "TST56jtUgZrajuBUgdECYaew6cebjSbKWVdtCKkc4xxLAFZQ9f8A9",
    "account_name": "memo-tnman"
  }
]

Every account on the testnet uses tnman as their account authority. Using this account, you can sign any transaction for any account.

Snapshot Refresh

Occasionally, it's a good idea to refresh the sample-snapshot.json file. This process is usually only required to be performed by the repo maintainer, but if you want to do it yourself, here are the steps:

1. Install tinman by following that product's README.md.
2. Next, generate a new snapshot.

• Example: tinman snapshot -s https://anyx.io -o - | pv > snapshot.json

3. Once we have our new snapshot, create a sample, overwriting the previous one.

• Example: tinman sample -i snapshot.json -o sample-snapshot.json

4. Delete (or move) snapshot.json (we don't need it anymore now that we have sample-snapshot.json).

# PostgreSQL Client Authentication Configuration File
# ===================================================
#
# Refer to the "Client Authentication" section in the PostgreSQL
# documentation for a complete description of this file.  A short
# synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which PostgreSQL user names they can use, which
# databases they can access.  Records take one of these forms:
#
# local      DATABASE  USER  METHOD  [OPTIONS]
# host       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
# hostssl    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
# hostnossl  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain
# socket, "host" is either a plain or SSL-encrypted TCP/IP socket,
# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
# plain TCP/IP socket.
#
# DATABASE can be "all", "sameuser", "samerole", "replication", a
# database name, or a comma-separated list thereof. The "all"
# keyword does not match "replication". Access to replication
# must be enabled in a separate record (see example below).
#
# USER can be "all", a user name, a group name prefixed with "+", or a
# comma-separated list thereof.  In both the DATABASE and USER fields
# you can also write a file name prefixed with "@" to include names
# from a separate file.
#
# ADDRESS specifies the set of hosts the record matches.  It can be a
# host name, or it is made up of an IP address and a CIDR mask that is
# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
# specifies the number of significant bits in the mask.  A host name
# that starts with a dot (.) matches a suffix of the actual host name.
# Alternatively, you can write an IP address and netmask in separate
# columns to specify the set of hosts.  Instead of a CIDR-address, you
# can write "samehost" to match any of the server's own IP addresses,
# or "samenet" to match any address in any subnet that the server is
# directly connected to.
#
# METHOD can be "trust", "reject", "md5", "password", "scram-sha-256",
# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert".
# Note that "password" sends passwords in clear text; "md5" or
# "scram-sha-256" are preferred since they send encrypted passwords.
#
# OPTIONS are a set of options for the authentication in the format
# NAME=VALUE.  The available options depend on the different
# authentication methods -- refer to the "Client Authentication"
# section in the documentation for a list of which options are
# available for which authentication methods.
#
# Database and user names containing spaces, commas, quotes and other
# special characters must be quoted.  Quoting one of the keywords
# "all", "sameuser", "samerole" or "replication" makes the name lose
# its special character, and just match a database or username with
# that name.
#
# This file is read on server startup and when the server receives a
# SIGHUP signal.  If you edit the file on a running system, you have to
# SIGHUP the server for the changes to take effect, run "pg_ctl reload",
# or execute "SELECT pg_reload_conf()".
#
# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records.  In that case you will also need to make PostgreSQL
# listen on a non-local interface via the listen_addresses
# configuration parameter, or via the -i or -h command line switches.




# DO NOT DISABLE!
# If you change this first entry you will need to make sure that the
# database superuser can access the database using some other method.
# Noninteractive access to all databases is required during automatic
# maintenance (custom daily cronjobs, replication, and similar tasks).
#
# Database administrative login by Unix domain socket
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             0.0.0.0/0            md5
# IPv6 local connections:
host    all             all             ::/0                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     peer

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
# "#" anywhere on a line.  The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, run "pg_ctl reload", or execute
# "SELECT pg_reload_conf()".  Some parameters, which are marked below,
# require a server shutdown and restart to take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on".  Some parameters can be changed at run time
# with the "SET" SQL command.
#

Just a quick note, I'm working on a branch that will embed hivemind, but it's currently blocked by steemit/hivemind#164. To try it out:

git clone https://gist.github.com/b88e7bfff8862858e54c59392e2bce20.git tintoy
cd tintoy
git checkout add-hivemind
docker build -t myname/tintoy:mybranch .
docker run -d -P myname/tintoy:mybranch

Then you can shell into the docker container and run:

source env.sh
./build-hivemind.sh
./start-hivemind.sh
