* delete reference to namespacesFranck Cuny2022-06-136-27/+21
| | | | | | We don't need namespaces, a better abstraction is to use different buckets, as this provides a better abstraction to manage quotas and permissions.
* github: don't install libpcapFranck Cuny2022-06-131-3/+0
| | | | There's no need to install the libpcap-dev package for this repo.
* github: fix workflow configurationFranck Cuny2022-06-131-1/+1
| | | | There's no `cmd` directory in this repo.
* github: add workflow configurationFranck Cuny2022-06-131-0/+38
| | | | | Let's ensure we test and build a binary when pushing to main and when we create a pull-request.
* add stub commands for buckitFranck Cuny2022-06-138-0/+130
| | | | | | | | | Add the stub commands for the binary. Each command will be in its own file (with the exception of delete/un-delete). This will make it easier to navigate the code. We use `github/urfave/cli` for generating the sub commands, as the module is well documented and easy to use.
* git: ignore the generated binary buckitFranck Cuny2022-06-131-0/+1

* initial documentationFranck Cuny2022-06-132-1/+63
| | | | This is a high level description of what buckit is and how it works.

* repo(containerd-to-vm): remove unneeded filesFranck Cuny2022-06-112-40/+0

* publish firecracker metrics in a FIFOFranck Cuny2022-06-111-2/+4
| | | | | We add a new argument to the CLI to collect the path where we want to publish the firecracker metrics.
* Makefile: install binaries and configsFranck Cuny2022-06-111-6/+23
| | | | | | | To help working on this project in the future, let's try to install dependencies and configurations with `make`. For now we know that we need the firecracker binary, the CNI configuration and the CNI plugin for TAP.
* rename the variable for the linux kernelFranck Cuny2022-06-111-7/+7
|
* c2vm: fix kernel boot optionsFranck Cuny2022-06-111-1/+1
| | | | | | | By specifying these options we can speed up the boot process from 0.9 second to 0.15 seconds. Without these options, the linux kernel spends a few milliseconds probing the device, which is useless in our context (see https://github.com/firecracker-microvm/firecracker/blob/main/docs/api_requests/actions.md#intel-and-amd-only-sendctrlaltdel)
* readme: update instructionsFranck Cuny2022-06-111-0/+16

* boot the VMFranck Cuny2022-06-113-4/+256
| | | | | | | | | The binary needs a few more arguments: the path to the firecracker binary, the path to a linux kernel. Using the image that was generated, we can now boot the VM with firecracker. This will rely on a CNI configuration to create the network, and will use the provided kernel to boot.
* hack: firecracker binary and CNI configurationFranck Cuny2022-06-113-0/+35
| | | | | | | | | Add a target to the Makefile to download a version of firecracker and extract it under the repository hack/firecracker. We will then use this binary for running the VM. Add a CNI configuration under hack/cni. This configuration will need to be copied to `/etc/cni/conf.d`.
* git: ignore binaryFranck Cuny2022-06-111-0/+1

* check for errorFranck Cuny2022-06-111-0/+3
| | | | | When reading the configuration for the container, if there's an error we return the error to the caller.
* github: add workflowsFranck Cuny2022-06-111-0/+35
| | | | Add a workflows to perform some validation when pushing new commits.
* inject a script for initFranck Cuny2022-06-111-0/+43
| | | | | | | | | Once we will be ready to boot our VM, we will need an init script in place. For this, we create a simple shell script which we populate using the environment variables and command extracted from the container. The init script is stored in /init.sh within the new image, and we will configure the boot parameter to find it there.
* extract layers to a mounted loop deviceFranck Cuny2022-06-113-1/+128
| | | | | | | | | | | | | We create a loop device by pre-allocating space to a file on disk. This file is then converted to an ext4 partition, which we mount to a temporary path on the host. Once this is done, we extract all the layers from the given container on that mounted path. We also add a few extra files to the image (`/etc/hosts` and `/etc/resolv.conf`). When we're done extracting and writing, we run resize2fs in order to resize the image to a more reasonable size.
* add a lease to the Go contextFranck Cuny2022-06-111-0/+6
| | | | | | | | | | | | This will ensure that our container will not be deleted while we work on it. In addition, a default expiry of 24 hours will be set on it once the lease is released (once the program is completed). See [1] for more details.

* pull a container into a namespaceFranck Cuny2022-06-114-0/+975
| | | | | | | | | | | | | | | | | | | | Pull an image provided as an argument to the program. We're only interested in images for Linux/amd64 at the moment. We setup a default namespace for containerd named `c2vm`. Images that will be pulled by containerd will be stored inside that namespace. Once the program is build it can be run like this: ``` ; sudo ./c2vm -container docker.io/library/redis:latest pulled docker.io/library/redis:latest (38667897 bytes) ``` And the image is indeed in the namespace: ``` ; sudo ctr -n c2vm images ls -q docker.io/library/redis:latest ```

* git: ignore binary for the REPLFranck Cuny2021-05-101-0/+1
|
* repl: support a simple REPL for some early testingfranck cuny2020-01-112-0/+41
| | | | | | The REPL reads the input, send it to the lexer, and prints the token to STDOUT. For now nothing else is done since we still don't parse the tokens.
* lexer: support tokens for equal and not equal.franck cuny2020-01-112-2/+39
| | | | | | | | | The tokens for equal (`==`) and not equal (`!=`) are composed of two characters. We introduce a new helper (`peekChar`) that we use when we encounter the token `=` or `!` to see if this is a token composed of two characters. Add some tests to ensure they are parsed correctly.
* token: add tokens for equal and not equal.franck cuny2020-01-111-0/+3

* lexer: test the new keywords are parsed correctly.franck cuny2020-01-111-3/+25
| | | | | Ensure that the new keywords added (`if`, `else`, `true`, `false`, `return`) are parsed correctly.
* token: support more keywordsfranck cuny2020-01-111-2/+13
| | | | | | | Add support for a few more keywords (`true`, `false`, `if`, `else`, `return`). All keywords are grouped together in the constant declaration.
* token: rewrite documentation for `LookupIdent`.franck cuny2020-01-111-3/+4

* lexer: delete redundant test.franck cuny2020-01-111-32/+1
| | | | | | | The test `TestNextTokenBasic` was not testing anything that `TestNextTokenMonkey` was not already testing. Rename `TestNextTokenMonkey` to `TestNextToken` for clarity.
* Makefile: add a Makefilefranck cuny2020-01-111-0/+4
| | | | For now, automate running the tests.
* lexer: support more operator tokens.franck cuny2020-01-112-1/+31
| | | | | Support the operator tokens that were added to our tokenizer. This also add a few more tests to ensure we handle them correctly.
* token: support more operator tokensfranck cuny2020-01-111-3/+10
| | | | | | Support additional tokens for operators (`-`, `*`, etc). This change only adds the tokens to the list of constants, and group all the tokens related to operators together.
* lexer: initial lexerfranck cuny2020-01-112-0/+218
| | | | | | | | | The initial lexer for the monkey language. We only support a small subset at this stage. We have some simple tests to ensure that we can parse some small snippet, and that the minimum number of tokens we need are also all supported correctly.
* token: initial tokenizer.franck cuny2020-01-111-0/+48
| | | | | | | | | | | This is the initial tokenizer for the monkey language. For now we recognize a limited number of tokens. We only have two keywords at this stage: `fn` and `let`. `fn` is used to create function, while `let` is used for assigning variables. The other tokens are mostly to parse the source code, and recognize things like brackets, parentheses, etc.
* go.mod: create the module 'monkey'franck cuny2020-01-111-0/+3
| | | | | | The project is named monkey, we add a mod file to ensure that the tooling / dependencies are set up correctly when we import various modules in this project.
