previously I could run my tests including colander parachain with polkadot:v0.9.18 or polkadot-debug... my network definition file:

[relaychain]
default_image = "docker.io/parity/polkadot:v0.9.18"
default_command = "polkadot"
default_args = [ "-lparachain=debug" ]

chain = "rococo-local"

  [[relaychain.nodes]]
  name = "alice"
  validator = true

  [[relaychain.nodes]]
  name = "bob"
  validator = true

[[parachains]]
id = 2000

  [parachains.collator]
  name = "collator01"
  image = "docker.io/paritypr/colander:master"
  command = "adder-collator"
  args = ["--parachain-id 2000"]

[types.Header]
number = "u64"
parent_hash = "Hash"
post_state = "Hash"

Now when I changed that colander image to my own parachain image:

[relaychain]
default_image = "docker.io/parity/polkadot:v0.9.18"
default_command = "polkadot"
default_args = [ "-lparachain=debug" ]

chain = "rococo-local"

  [[relaychain.nodes]]
  name = "alice"
  validator = true

  [[relaychain.nodes]]
  name = "bob"
  validator = true

[[parachains]]
id = 2000
cumulus_based = true

  [parachains.collator]
  name = "collator01"
  image = "gcr.io/p-network-202104/collator:v4"
  command = "target/release/parachain-collator"

[types.Header]
number = "u64"
parent_hash = "Hash"
post_state = "Hash"

And my tests:

Description: Small Network test
Network: ./z05-small-network.toml
Creds: config

# to run this file: ./zombienet-linux -p kubernetes test zombienet/z05-small-network.feature

# well know functions
alice: is up
bob: is up
alice: parachain 2000 is registered within 225 seconds

# logs
bob: log line matches glob "*rted #1*" within 10 seconds
bob: log line matches "Imported #[0-9]+" within 10 seconds
bob: log line matches "Imported new block." within 10 seconds

alice: parachain 2000 block height is at least 6 within 150 seconds

# Tracing
# alice: trace with traceID 94c1501a78a0d83c498cc92deec264d9 contains ["answer-chunk-request", "answer-chunk-request"]

# metrics

alice: reports sub_libp2p_is_major_syncing is 0

# system events
bob: system event contains "A candidate was included" within 20 seconds
alice: system event matches glob "*was backed*" within 10 seconds

Then I got this command output:

From above you can see the

  • relaychain alice node test: ok
  • relaychain bob node test: ok
  • parachain 2000 is registered: ok
  • 3 log tests: ok
  • parachain 2000 block height test: failed!!?? Why did that fail?

When I was using docker.io/paritypr/colander:master, the block height test was successful...

Especially when I checked the collator logs via kubectl logs -f collator01 -c collator01 -n zombie-8a529a22b7767d93655b4bb89b74e034 I got:

What is wrong?

My Dockerfile.base:

SHELL ["bash", "-lc"]
RUN rustup update
RUN rustup update nightly
RUN rustup target add wasm32-unknown-unknown --toolchain nightly

CMD [ "tail", "-f", "/dev/null" ]

And my Dockerfile:

ARG PROFILE=release
WORKDIR /builds/collator

COPY . .

RUN . $HOME/.cargo/env && cargo build --${PROFILE}

# TODO: Make this run the CMD used in the docker-compose-collator.yaml
CMD tail -f /dev/null

Is there any argument missing in my Zombienet network definition file?

looks like your parachain collator is based on cumulus (and not on one of the testnet like adder-collator), in that case you need to use the flag cumulus_based in the parachain definition.

[relaychain]
default_image = "docker.io/parity/polkadot:v0.9.18"
default_command = "polkadot"
default_args = [ "-lparachain=debug" ]

chain = "rococo-local"

  [[relaychain.nodes]]
  name = "alice"
  validator = true

  [[relaychain.nodes]]
  name = "bob"
  validator = true

[[parachains]]
id = 2000
cumulus_based = true

  [parachains.collator]
  name = "collator01"
  image = "gcr.io/p-network/collator:latest"
  command = "target/release/parachain-collator"
  args = ["--parachain-id 2000"]

[types.Header]
number = "u64"
parent_hash = "Hash"
post_state = "Hash"

Thanks!

  • Hi @Russo, is this the error Error: Input("Error parsing spec file: missing field relay_chain` at line 155 column 1")`, in this case looks like the chain-spec is wrong. Are the image public for try to reproduce?
