Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

Changed

  • Container::exec changed to be synchronous and return ExecOutput

Removed

  • Removed all pre-defined images from the library to escape unbounded maintenance work. See testcontainers#471 for details.

0.14.0 - 2022-05-30

Added

  • Added watchdog feature that spawns a background thread keeping track of docker containers that are started by the test suite and removes them in the case of a CTRL+C or kill of the test process.
  • Introduced Container::get_host_port_ipv4, Container::get_host_port_ipv6, ContainerState::host_port_ipv4, and ContainerState::host_port_ipv6 to better handle automatically assigned ports. Docker may bind the same exposed container port to different host ports on 0.0.0.0 and ::, depending on influences from the environment.

Changed

  • Container::get_host_port and ContainerState::host_port are now deprecated in favor of the new IPv4- and IPv6-specific methods.
  • MSRV is now 1.60.

0.13.0 - 2022-04-04

Added

  • A new client implementation that talks to the Docker daemon via HTTP. This implementation is available as testcontainers::clients::Http and provides an async interface. As of now, this implementation is guarded behind the experimental feature-flag and not yet guaranteed to work flawlessly.
  • Allow using podman CLI in addition to docker
  • The TESTCONTAINERS environment variable to control what happens to containers and networks at the end of a test. The default value is remove which deletes all containers and networks that were used in the test. By setting the value to keep, containers and networks will not be deleted but kept running. You will have to stop and delete those yourself eventually.
  • Upgrade default bitcoin-core image version to 0.21.0. This allows us to remove -debug for bitcoind and replace it with -startupnotify=echo .... More details on bitcoind 0.21.0 can be found here. Note: This release also removed the default wallet.
  • expose_port functionality to Image trait.
  • Google Cloud SDK image
  • RabbitMQ image
  • WaitFor::Healthcheck container ready condition, which corresponds with the healthcheck status.
  • MinIO image

Changed

  • How images express when a container is ready: Instead of implementing wait_until_ready, images now need to implement ready_conditions which returns a list of WaitFor instances.
  • Return value of get_host_port from Option<u16> to u16. If the port cannot be resolved, this function will now panic.
  • MSRV bumped to 1.46.
  • Make Docker trait pub(crate). This reduces the API surface of the crate which allows for fewer breaking changes in the future. All functionality from Docker (start, stop, rm, and ports) is available on a container directly.
  • descriptor is broken down into name and tag within Image trait.
  • Bump MongoDB-image default version to 5.0.6.

Removed

  • DYNAMODB_ADDITIONAL_SLEEP_PERIOD variable from dynamodb_local image. Previously, we had a fallback of 2 seconds if this variable was not defined. We now wait for 2 seconds unconditionally after the specified message has been found.
  • Support for the KEEP_CONTAINERS env variable. The functionality of KEEP_CONTAINERS=true is superseded by TESTCONTAINERS=keep.
  • with_entrypoint from the Image trait. This functionality is not used within the library. Images that need this kind of customization can always implement it on their own type directly but there is no need to force it onto them.
  • Image::EnvVars and Image::Volumes associated types. The respective functions Image::env_vars and Image::volumes still exist but now return a trait object that must implement Iterator<Item = (&String, &String). This allows us to provide a default implementation which reduces the boilerplate in defining new images.
  • args and with_args from Image trait.

Fixed

  • Removing a docker container did not error if failed. This was fixed by asserting the daemon's response instead of just the status code: If a docker container was removed correctly using rm -f -v <ID> is printed on stdout. can either be the container name or its ID which is used within testcontainer-rs.
  • Fixed clippy warnings of camel case names containing a capitalized acronym.

0.12.0 - 2021-01-27

Added

  • Allow custom version for postgres image
  • Remove derivative dependency
  • OrientDB image
  • Zookeeper image

Changed

  • Move port mapping logic to RunArgs instead of each Image.

0.11.0 - 2020-09-30

Added

  • Docker::run_with_args method. This allows naming a container and assigning it to a specific docker network. The docker network will be created if it doesn't exist yet. Once the client is dropped, the network will be removed again if it has previously been created. A network that already existed will not be removed.
  • Address-type argument to coblox/bitcoin-core Image. We are setting bech32 as a default here. This is different from the default of bitcoind.

Fixed

  • Block the thread until containers have been successfully removed. Previously, this was done in a fire-and-forget way and hence led to containers not being removed in certain situations.

Changed

  • MSRV is now 1.41.0

0.10.0 - 2020-08-20

Added

  • Mongo image.
  • Support for the fallbackfee argument for the bitcoin-core image.
  • Ability to customize the entrypoint used by the image.
  • Ability to start a container once stopped.

Changed

  • MSRV bumped to 1.36 from 1.32.
  • Change postgres image authentication POSTGRES_HOST_AUTH_METHOD rather than username and password.
  • Bumped bitcoin-core default tag to 0.20.0.

0.9.1 - 2020-03-24

Added

  • A changelog
  • Support volumes on containers

Changed

  • Breaking: Container#get_host_port now only accepts a u16 instead of a u32. u16 captures all possible port values.

Fixes

  • Provide a default password for the postgres image. There seems to be an unfortunate breaking change in the postgres image that we need to cater for.
