Migration guides

0.6.x-beta -> 0.7.x-beta

ALERTA, ALERTA: this is currently only available via the release candidate channel, using abra upgrade --rc. There has been a lot of churn and we're being cautious about releasing this one. Please help us test! We're currently on 0.7.0-rc2-beta.

  • kadabra, the app auto-updater is available for general alpha testing! See these docs for how to get started. Binaries can be found here.

  • ALERTA, ALERTA, security related issue: all $domain.env env vars are now exposed to the deployment via the app service container. Each FOO=BAR is exported within the context of the container. If you have any privately committed secrets in your .env files, please migrate them to the secrets: ... configuration in the recipe. This change was made to facilitate tooling which can support auto-upgrading of apps in a deployment.

  • abra can no longer install Docker, initialise swarm mode and the proxy network. It will check if a Docker install exists and is in swarm mode or not and error out accordingly. We leave the provisioning to tools that are designed for that and reduce the command-line surface that we have to maintain going forward.

  • abra server add <host> <args> 👉 abra server add <host>. We have finally removed the custom SSH handling code and now solely rely on invoke /usr/bin/ssh directly and reading from the ~/.ssh/config. The <host> argument should correspond to a Host <host> entry in your ~/.ssh/config or in an Include <file> statement (hosts are retrieved via ssh -G <host>). This means "how does abra interact with SSH is 1) do you have an ~/.ssh/config entry for <host> 2) can you ssh <host> successfully? 3) there is no 3. It's an easier mental model and also the way abra-bash works, hence, less weird obscure errors. <host> being public a domain name is still required.

  • abra no longer tries to do the TOFU host key verification prompt. We follow the praxis of the Docker CLI and just give up when host keys are not validated. We leave it to folks to SSH in and verify themselves.

  • On the way to kadabra, several changes regarding labelling deployments have been merged in this release. This will allow tooling to understand a deployment without having the context of a ~/.abra/... configuration. This will pave the way for server-side tooling, like kadabra which can help operators with different kinds of maintenance tasks.

  • Welcome abra recipe fetch, which helps retrieve a recipe repository to your local work-station.

  • Also say hello to abra app services <domain>, which lists the in-deployment service names and corresponding image, e.g. foo_example_com.

  • Digests have been removed from the catalogue generation.

  • Backup files generated by abra have a much more human-friendly format.

  • Linting for domains is disabled when no DOMAIN=... is discovered in the $odmain.env file.

0.5.x-beta -> 0.6.x-beta

  • Using {{ .Domain }} in recipe .envrc.sample files went away because it was portable enough. We revert to replacing e.g gitea.example.com with the domain. See 8fad34e for more.

  • If your abra.sh scripts depend on /bin/sh and /bin/bash is available in the container then /bin/bash will be used from now on. /bin/sh is only now used if /bin/bash is not available. See 7f745ff for more.

v0.4.x -> v0.5.x

v0.3.x -> v0.4.x

Make sure to back up your ~/.abra/servers configurations first for safety.

  • Please run mv ~/.abra/apps ~/.abra/recipes.

  • "app name" as a concept went away, abra now uses the domain name of an app as the identifier. However, we don't expect to see breaking behaviour if you have .env files like ~/.abra/servers/foo.com/mycoolapp.env and you still want to run abra app ps mycoolapp. abra still reads the filename to figure out the identifier. When running abra app new <recipe>, abra will now take the domain name as the name of the .env file.

  • abra has a new SSH implementation which enforces SSH host key checking. You may run into connection issues as a result of this code churn, please see this entry for help navigating a fix.

  • CLI flag/args handling has been made more flexible. We're working within the constraints of an upstream library issue but have hopefully made it easier to mange passing flags to commands with abra. See this troubleshooting entry for the full review.

  • A number of short style flags have been re-mapped and/or added. This is again related to an issue with the upstream CLI library which sometimes understands short style flags as long style flags. E.g. --ch instead of -ch for --chaos. As a concrete example, --ch is now -C on abra app deploy.

  • abra app backup & abra app restore are ready for alpha-testing! See this entry and that entry for more.

  • abra server add --traefik went away, it was too unreliable & hard to maintain.
