=== The easiest way
|
||
|
||
The easiest/faster option is to use the latest image.
|
||
|
||
Let´s first check the version we have. The first time you run this command, the polkadot docker image will be downloaded. This takes a bit of time and bandwidth, be patient:
|
||
|
||
[source, shell]
|
||
docker run --rm -it chevdor/polkadot:0.3.14 polkadot --version
|
||
|
||
You can also pass any argument/flag that polkadot supports:
|
||
|
||
[source, shell]
|
||
docker run --rm -it chevdor/polkadot:0.3.14 polkadot --chain alex --name "PolkaDocker"
|
||
|
||
Once you are done experimenting and picking the best node name :) you can start polkadot as daemon, exposes the polkadot ports and mount a volume that will keep your blockchain data locally:
|
||
|
||
[source, shell]
|
||
docker run -d -p 30333:30333 -p 9933:9933 -v /my/local/folder:/data chevdor/polkadot:0.3.14 polkadot --chain alex
|
||
|
||
Additionally if you want to have custom node name you can add the `--name "YourName"` at the end
|
||
|
||
[source, shell]
|
||
docker run -d -p 30333:30333 -p 9933:9933 -v /my/local/folder:/data chevdor/polkadot:0.3.14 polkadot --chain alex --name "PolkaDocker"
|
||
|
||
**Note:** The `--chain alex` argument is important and you need to add it to the command line. If you are running older node versions (pre 0.3) you don't need it.
|
||
|
||
Start a shell session with the daemon:
|
||
|
||
[source, shell]
|
||
docker exec -it $(docker ps -q) bash;
|
||
|
||
Check the current version:
|
||
|
||
[source, shell]
|
||
polkadot --version
|
||
|
||
|
||
=== Build your own image
|
||
|
||
To get up and running with the smallest footprint on your system, you may use the Polkadot Docker image.
|
||
You can build it yourself (it takes a while...) in the shell session of the daemon:
|
||
|
||
[source, shell]
|
||
----
|
||
cd docker
|
||
./build.sh
|
||
----
|
||
|
||
=== Reporting issues
|
||
|
||
If you run into issues with polkadot when using docker, please run the following command
|
||
(replace the tag with the appropriate one if you do not use latest):
|
||
|
||
[source, shell]
|
||
docker run --rm -it chevdor/polkadot:latest polkadot version
|
||
|
||
This will show you the polkadot version as well as the git commit ref that was used to build your container.
|
||
Just paste that in the issue you create.
