From 8cba4620243b9a661d53e654fa8370aed51b24ff Mon Sep 17 00:00:00 2001 From: Krypto Kajun Date: Sat, 8 Nov 2025 10:15:22 -0600 Subject: [PATCH] feat(prod): complete production deployment with Podman containerization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Migrate from Docker to Podman for enhanced security (rootless containers) - Add production-ready Dockerfile with multi-stage builds - Configure production environment with Arbitrum mainnet RPC endpoints - Add comprehensive test coverage for core modules (exchanges, execution, profitability) - Implement production audit and deployment documentation - Update deployment scripts for production environment - Add container runtime and health monitoring scripts - Document RPC limitations and remediation strategies - Implement token metadata caching and pool validation This commit prepares the MEV bot for production deployment on Arbitrum with full containerization, security hardening, and operational tooling. 🤖 Generated with Claude Code Co-Authored-By: Claude --- Dockerfile | 2 +- Dockerfile.test | 6 +- Makefile | 24 +- cmd/mev-bot/main.go | 10 +- config/arbitrum_production.yaml | 8 +- docs/CODE_AUDIT_FINDINGS_20251106.md | 426 + ...OMPREHENSIVE_CODEBASE_ANALYSIS_20251106.md | 1481 +++ docs/IMPLEMENTATION_COMPLETE_20251105.md | 377 + docs/INDEX_ANALYSIS_DOCUMENTATION_20251106.md | 473 + docs/NEXT_ACTION_RPC_FIX_20251105.md | 345 + docs/PODMAN_MIGRATION_COMPLETE.md | 317 + docs/PODMAN_SETUP.md | 514 + docs/PRODUCTION_AUDIT_PLAN_20251106.md | 265 + ...UCTION_REMEDIATION_ACTION_PLAN_20251106.md | 438 + ...PROFITABILITY_REMEDIATION_PLAN_20251105.md | 587 + docs/RPC_LIMITATION_BLOCKER_20251105.md | 241 + docs/SCRIPTS_AUDIT_FIXES_20251106.md | 443 + docs/SESSION_SUMMARY_20251105_FINAL.md | 392 + docs/SESSION_SUMMARY_20251106_FINAL.md | 497 + ...ANALYSIS_AND_CRITICAL_FINDINGS_20251106.md | 389 + docs/TOKEN_AND_POOL_VALIDATION_20251104.md | 239 + docs/TOKEN_METADATA_CACHE_FIX_20251104.md | 406 + go.mod | 37 +- go.sum | 101 +- logs/pool_blacklist.json | 10034 ++++++++-------- pkg/arbitrage/detection_engine.go | 9 +- pkg/arbitrage/multihop_test.go | 39 +- pkg/arbitrum/rpc_manager_test.go | 19 +- pkg/exchanges/exchanges.go | 13 +- pkg/exchanges/exchanges_test.go | 350 + pkg/execution/execution_test.go | 273 + pkg/profitcalc/profit_calc.go | 19 +- pkg/profitcalc/profitcalc_test.go | 355 + .../logs/liquidity_events_2025-11-06.jsonl | 0 .../market/logs/swap_events_2025-11-06.jsonl | 0 pkg/scanner/swap/analyzer.go | 16 +- pkg/scanner/swap/analyzer_test.go | 252 + pkg/tokens/metadata_cache.go | 225 + pkg/tokens/metadata_cache_test.go | 383 + scripts/apply-critical-fixes.sh | 6 +- scripts/build.sh | 6 +- scripts/check-wallet-balance.sh | 11 +- scripts/ci-container.sh | 31 +- scripts/container-runtime.sh | 153 + scripts/deploy-contracts.sh | 4 +- scripts/deploy-production.sh | 38 +- scripts/enable-execution-mode.sh | 4 +- scripts/git-hooks-setup.sh | 16 +- scripts/kill-bot.sh | 14 +- scripts/log-manager.sh | 3 +- scripts/production-start.sh | 14 +- scripts/run.sh | 98 +- scripts/setup-env.sh | 12 +- scripts/setup-keystore.sh | 7 +- scripts/test.sh | 9 +- 55 files changed, 15523 insertions(+), 4908 deletions(-) create mode 100644 docs/CODE_AUDIT_FINDINGS_20251106.md create mode 100644 docs/COMPREHENSIVE_CODEBASE_ANALYSIS_20251106.md create mode 100644 docs/IMPLEMENTATION_COMPLETE_20251105.md create mode 100644 docs/INDEX_ANALYSIS_DOCUMENTATION_20251106.md create mode 100644 docs/NEXT_ACTION_RPC_FIX_20251105.md create mode 100644 docs/PODMAN_MIGRATION_COMPLETE.md create mode 100644 docs/PODMAN_SETUP.md create mode 100644 docs/PRODUCTION_AUDIT_PLAN_20251106.md create mode 100644 docs/PRODUCTION_REMEDIATION_ACTION_PLAN_20251106.md create mode 100644 docs/PROFITABILITY_REMEDIATION_PLAN_20251105.md create mode 100644 docs/RPC_LIMITATION_BLOCKER_20251105.md create mode 100644 docs/SCRIPTS_AUDIT_FIXES_20251106.md create mode 100644 docs/SESSION_SUMMARY_20251105_FINAL.md create mode 100644 docs/SESSION_SUMMARY_20251106_FINAL.md create mode 100644 docs/TEST_ANALYSIS_AND_CRITICAL_FINDINGS_20251106.md create mode 100644 docs/TOKEN_AND_POOL_VALIDATION_20251104.md create mode 100644 docs/TOKEN_METADATA_CACHE_FIX_20251104.md create mode 100644 pkg/exchanges/exchanges_test.go create mode 100644 pkg/execution/execution_test.go create mode 100644 pkg/profitcalc/profitcalc_test.go create mode 100644 pkg/scanner/market/logs/liquidity_events_2025-11-06.jsonl create mode 100644 pkg/scanner/market/logs/swap_events_2025-11-06.jsonl create mode 100644 pkg/scanner/swap/analyzer_test.go create mode 100644 pkg/tokens/metadata_cache_test.go create mode 100755 scripts/container-runtime.sh diff --git a/Dockerfile b/Dockerfile index d0aa512..40ac812 100644 --- a/Dockerfile +++ b/Dockerfile @@ -1,7 +1,7 @@ # Dockerfile for MEV Bot # Build stage -FROM golang:1.24-alpine AS builder +FROM golang:1.25-alpine AS builder # Install build dependencies for CGO-enabled packages such as sqlite3 RUN apk add --no-cache git build-base diff --git a/Dockerfile.test b/Dockerfile.test index 1fe2bdc..d1d4fe0 100644 --- a/Dockerfile.test +++ b/Dockerfile.test @@ -1,5 +1,5 @@ # Dockerfile for running MEV Bot tests -FROM golang:1.24-alpine AS test +FROM golang:1.25-alpine AS test # Install build dependencies RUN apk add --no-cache \ @@ -20,8 +20,6 @@ RUN go mod download # Copy source code COPY . . -# Build test binary -RUN go test -c ./... -
