¿Cómo ejecutar un nodo Tezos en espacio aislado en un contenedor Docker?

Estoytratando deejecutar unnodotezosen unespacio aisladoen un contenedor Docker. Dado que (enmi opinión)noesposible usar laimagennormal de la ventana acoplable detezos,ytuveproblemas al usar granero ,intenté configurar un contenedor Docker usandoel siguiente Dockerfile:

 FROM ubuntu:18.04
RUN apt-get update -y
RUN apt-get install -y rsync git m4 build-essential patch unzip bubblewrap wget pkg-config libgmp-dev libev-dev libhidapi-dev libsodium-dev libcurl4-gnutls-dev ocaml
RUN apt-get install -y libgmp-dev m4 perl
RUN wget https://github.com/ocaml/opam/releases/download/2.0.3/opam-2.0.3-x86_64-linux
RUN cp opam-2.0.3-x86_64-linux /usr/local/bin/opam
RUN chmod a+x /usr/local/bin/opam
RUN git clone https://github.com/ocaml/dune.git
WORKDIR /dune/
RUN make release
RUN make install
WORKDIR /
RUN git clone https://gitlab.com/tezos/tezos.git
WORKDIR /tezos/
RUN git checkout alphanet
RUN opam init --bare --disable-sandboxing
RUN eval $(opam env)
RUN make build-deps
RUN eval $(opam env)
RUN opam update && opam upgrade -y
RUN opam config exec make
RUN export PATH=/tezos:$PATH
# RUN source ./src/bin_client/bash-completion.sh
RUN export TEZOS_CLIENT_UNSAFE_DISABLE_DISCLAIMER=Y
COPY ./start-tezos-sandbox.sh .
ENTRYPOINT ["./start-tezos-sandbox.sh"]
 

start-tezos-sandbox.shtiene el siguiente aspecto:

 #!/usr/bin/env bash

DATA_DIR='/var/run/tezos/node' /tezos/src/bin_node/tezos-sandboxed-node.sh 1 --connections 1 &
P1=$!
eval 'sleep 5 && eval '/tezos/src/bin_client/tezos-init-sandboxed-client.sh 1'' &
P2=$!
wait $P2
/tezos/src/bin_client//../../_build/default/src/bin_client/main_client.exe -base-dir /var/run/tezos/client -addr localhost -port 18731 -block genesis activate protocol Pt24m4xiPbLDhVgVfABUjirbmda3yohdN82Sp9FeuAXJ4eV9otd with fitness 1 and key activator and parameters /tezos/src/bin_client//../../scripts/protocol_parameters.json --timestamp 2019-06-21T11:20:44Z
wait $P1
 

Elnodo seinicia como seesperaba,pero laejecución del comandopara activarelprotocolo alfa (es decir,lo quetiene el alias de tezos-activate-alpha)noparecefuncionar. En cambio,eltercer comando de start-tezos-sandbox.sh soloproduce:

 Error:
  No matching plugin for key scheme 
 

Noestoy seguro de quéestá causandoesteerror,e incluso siejecutar unnodo deespacio aislado comoesteeselenfoque correcto. ¿Hay alguna otraforma deejecutar unnodo deespacio aislado como contenedor de Docker? ¿O sepuede solucionaresteerror? ¡Cualquier ayuda será apreciada!

¡Gracias!

I'm trying to run a sandboxed tezos node in a Docker container. Since it's (to my mind) not possible using the normal tezos docker image, and I ran into issues using granary, I tried setting up a Docker container using the following Dockerfile:

FROM ubuntu:18.04
RUN apt-get update -y
RUN apt-get install -y rsync git m4 build-essential patch unzip bubblewrap wget pkg-config libgmp-dev libev-dev libhidapi-dev libsodium-dev libcurl4-gnutls-dev ocaml
RUN apt-get install -y libgmp-dev m4 perl
RUN wget https://github.com/ocaml/opam/releases/download/2.0.3/opam-2.0.3-x86_64-linux
RUN cp opam-2.0.3-x86_64-linux /usr/local/bin/opam
RUN chmod a+x /usr/local/bin/opam
RUN git clone https://github.com/ocaml/dune.git
WORKDIR /dune/
RUN make release
RUN make install
WORKDIR /
RUN git clone https://gitlab.com/tezos/tezos.git
WORKDIR /tezos/
RUN git checkout alphanet
RUN opam init --bare --disable-sandboxing
RUN eval $(opam env)
RUN make build-deps
RUN eval $(opam env)
RUN opam update && opam upgrade -y
RUN opam config exec make
RUN export PATH=/tezos:$PATH
# RUN source ./src/bin_client/bash-completion.sh
RUN export TEZOS_CLIENT_UNSAFE_DISABLE_DISCLAIMER=Y
COPY ./start-tezos-sandbox.sh .
ENTRYPOINT ["./start-tezos-sandbox.sh"]

start-tezos-sandbox.sh looks as follows:

#!/usr/bin/env bash

DATA_DIR='/var/run/tezos/node' /tezos/src/bin_node/tezos-sandboxed-node.sh 1 --connections 1 &
P1=$!
eval 'sleep 5 && eval '/tezos/src/bin_client/tezos-init-sandboxed-client.sh 1'' &
P2=$!
wait $P2
/tezos/src/bin_client//../../_build/default/src/bin_client/main_client.exe -base-dir /var/run/tezos/client -addr localhost -port 18731 -block genesis activate protocol Pt24m4xiPbLDhVgVfABUjirbmda3yohdN82Sp9FeuAXJ4eV9otd with fitness 1 and key activator and parameters /tezos/src/bin_client//../../scripts/protocol_parameters.json --timestamp 2019-06-21T11:20:44Z
wait $P1

The node starts as expected, but executing the command to activate the alpha protocol (i.e., what's aliased to tezos-activate-alpha) does not seem to work. Instead, the third command of start-tezos-sandbox.sh only yields:

Error:
  No matching plugin for key scheme 

I'm not sure what's causing this error, and even whether running a sandboxed node like this is the correct approach. Is ther any other way to run a sandbox node as a Docker container? Or can this error be fixed? Any help would be appreciated!

Thanks!
