# Uncomment this section to enable the explicit definition of hosts in your

#
# Specs is an array of Spec entries. Each Spec entry consists of two fields:
# - Hostname: (Required) The desired hostname, sans the domain.
# - CommonName: (Optional) Specifies the template or explicit override for
# the CN. By default, this is the template:
#
# "{
{.Hostname}}.{
{.Domain}}"
#
# which obtains its values from the Spec.Hostname and
# Org.Domain, respectively.
# ---------------------------------------------------------------------------
# Specs:
# - Hostname: foo # implicitly "foo.org1.example.com"
# CommonName: foo27.org5.example.com # overrides Hostname-based FQDN set above
# - Hostname: bar
# - Hostname: baz
# ---------------------------------------------------------------------------
# "Template"
# ---------------------------------------------------------------------------
# Allows for the definition of 1 or more hosts that are created sequentially
# from a template. By default, this looks like "peer%d" from 0 to Count-1.
# You may override the number of nodes (Count), the starting index (Start)
# or the template used to construct the name (Hostname).
#
# Note: Template and Specs are not mutually exclusive. You may define both
# sections and the aggregate nodes will be created for you. Take care with
# name collisions

# SECTION: Capabilities
#
# - This section defines the capabilities of fabric network. This is a new
# concept as of v1.1.0 and should not be utilized in mixed networks with
# v1.0.x peers and orderers. Capabilities define features which must be
# present in a fabric binary for that binary to safely participate in the
# fabric network. For instance, if a new MSP type is added, newer binaries
# might recognize and validate the signatures from this type, while older
# binaries without this support would be unable to validate those
# transactions. This could lead to different versions of the fabric binaries
# having different world states. Instead, defining a capability for a channel
# informs those binaries without this capability that they must cease
# processing transactions until they have been upgraded. For v1.0.x if any
# capabilities are defined (including a map with all capabilities turned off)
# then the v1.0.x peer will deliberately crash.

Configure docker-compose-cli.yaml , docker-compose-etcdraft2.yaml , base.yaml en el directorio helloworld
El archivo de configuración se escribe con referencia al archivo de configuración en first-network ; el código repetido se coloca en base.yaml para evitar la redundancia de código y hacerlo más legible.

3. Inicie la red Fabric
Nota: Al cerrar la red Fabric, presione -v (eliminar volumen)
1. Inicie docker-compose-cli.yaml
docker-compose -f docker-compose-cli.yaml up -d
2. Inicie docker-compose-etcdraft2.yaml
docker-compose -f docker-compose-etcdraft2.yaml up -d
3. Inicie el contenedor cli
docker exec -it cli bash
4. Crea un canal
ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls --cafile $ORDERER_CA
5. Agregue Peer al canal
peer channel join -b channel001.block
4. Instale y ejecute el contrato inteligente.
