IPFS in Docker

Usage

Start the IPFS:

docker-compose up -d

This will initialize the node under data/.ipfs directory.

Then prepare the following functions and add them to your ~/.bash_aliases file:

function docker_helper_up() {
  command cd ~/git/$1
  docker-compose up -d "$1"
  command cd ~-
}

function docker_helper_exec_u() {
  command cd ~/git/$1
  docker-compose exec -w /home/user -u user "$1" "$@"
  command cd ~-
}

function ipfs-daemon() {
  docker_helper_up ipfs
}

function ipfs() {
  docker_helper_exec_u "$FUNCNAME" "$@"
}

Now you can use ipfs command as normal:

$ ipfs-daemon
$ ipfs id
$ ipfs swarm addrs --local
$ ipfs pin ls -q --type recursive
$ ipfs ls QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv
$ ipfs cat QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv/quick-start

$ mkdir data/public
$ cp ~/Downloads/dog-on-moon.gif data/public
$ ipfs add -rw public

$ ipfs ls Qmdd7jNjEM4RXEnG8Y4ZikaqN6PUJkZ6bZuJZySEaFcuqY
