+# EOS-playground
+
+The easiest way to start develop smart contracts in the EOS Blockchain with Docker
+
+### Set up
+
+```
+git clone https://github.com/grigio/eos-playground.git
+
+# latest official docker images images
+docker pull eosio/eos && \
+docker pull eosio/builder && \
+docker pull mongo
+
+# persistance
+docker volume create mongo-data-volume && \
+docker volume create nodeos-data-volume && \
+docker volume create keosd-data-volume
+
+# latest example EOS smart contracts
+svn export https://github.com/eosio/eos.git/trunk/contracts playground/contracts
+
+```
+
+You can customize which commands to run at startup in the EOS playground environment
+
+```
+cp bashrc.example bashrc
+```
+
+### Let's enter in the EOS Development Environment!
+
+When you need, you can run the commands below in 2 terminal windows. The execution order is important.
+
+```
+# terminal 1 - Blockchain logs
+docker-compose up
+
+# terminal 2 - Interactive EOS environment, eosiocpp, cleos, ..
+docker-compose exec -u $( id -u $USER ) builder bash --rcfile /bashrc
+```
+
+To test that all the pieces are fine together you can run:
+
+```
+playground❯ cleos get info
+{
+  "server_version": "2ae61517",
+  "head_block_num": 361,
+  "last_irreversible_block_num": 360,
+  "head_block_id": "000001697eeb23ecab64cf78365c3ef5c959c543bf4d495c5b79c2ec5456480a",
+  "head_block_time": "2018-05-09T06:54:30",
+  "head_block_producer": "eosio"
+}
+```
+
+You should see the block num increasing.
+
+## Clean up
+
+```
+# Reset the persistant data
+docker-compose down
+docker volume rm  mongo-data-volume && \
+docker volume rm  nodeos-data-volume && \
+docker volume rm keosd-data-volume
+
+rm -rfv playground/contracts
+```
